Hello and welcome to everything I have ever known about making a gluten free sourdough starter from scratch. Although there is a starter recipe (and lots of sweet and savoury recipes) in my cookbook, I wanted to create this guide to answer every and any question without any space constraints. I hope that you will find this gluten free sourdough starter recipe helpful. If you have any burning questions, please ask me! I love chatting all things gluten free sourdough.
How to make a gluten free sourdough starter
A gluten free sourdough starter is a simple mix of flour and water which is fed daily. Over the course of 6-10 or so days, this mixture grows in size. It forms large bubbles which are capable of raising a loaf of bread. A sourdough starter is essentially a living version of packet yeast. It is, however, way better for you and way better for your digestion.
If you’ve ever googled sourdough starters, you might have been turned off by the amount of technical feeding schedules and lingo. I know I was. However, I personally have found (on multiple occasions, so it’s not beginners luck) that the process can be a lot more free flowing than this. Once you get the hang of it and your starter is up and running, it can take a lot more than you’d expect.
To begin a gluten free sourdough starter, I use equal parts gluten free flour and water by weight. Sometimes you will see 100% hydration written, and this means that the starter has been made with equal parts flour and water. Personally, I often (to the horror of precise bakers, I’m sure) add water by sight as opposed to weight – I want my starter to be thick and paste like but not dry. More on this later.
A growing starter is fed twice a day, once in the morning and once at night. Consider it your new pet that doesn’t leave deposits on the carpet or make any noise.
What is gluten free sourdough starter?
Gluten free sourdough starter is wild yeast made from fermenting gluten free flour with water. Over the course of 7-10 days of feeding and discarding, the mixture gains enough strength to work in the same manner as commercial yeast. When added to sourdough bread recipes, it will enable to loaf to rise, creating an airy crumb.
Is it easy to make a gluten free sourdough starter?
Making a gluten free sourdough starter is an easy process. It involves a bit of attention to detail in the beginning, but once a starter is established it can be quite resilient.
The hardest part of making a gluten free sourdough starter is knowing when to be patient and when to give up in the formative stages. Some starters never take off (it has happened to me) and some do. I would say this is the only difficult part. Aside from, of course, remembering to feed it.
What is hydration?
You will often see sourdough starter recipes (and bread recipes) mention hydration. 100% hydration means that you have added equal parts flour and water. 125% hydration, as an example, would mean you have added 100g flour and 125g water.
Gluten free sourdough starter recipes often need more hydration than regular ones. This is because gluten free flours generally absorb more water than wheat flour.
What is discard?
We will go into this a little more below, but you will often read about discarding starter. Because you are adding 2 lots of water and flour each day, a sourdough starter can quickly become unwieldy. It also requires even more food the larger it is, so discarding is a way of keeping your starter small. It also removes waste product from the fermentation process, keeping the starter nice and healthy.
Initially I was pretty against discarding so much flour. It seemed incredibly wasteful and pointless. I didn’t discard precisely (still don’t) and I didn’t do it often. So now I can say with a reasonable amount of experience under my belt: a starter that has had a good schedule of discarding makes better bread. Sure, you can make a loaf with a bubbly starter that hasn’t had any discarding. It works. However, a starter that has had the waste product removed is healthier and stronger. It is in a better position to give you the gluten free sourdough you’ve always dreamed of. Given that the starter is the most critical ingredient in a sourdough, why not give it all the chance you can?
Another important thing to note with discard is that any use of your starter counts. So, if you’re baking bread daily, that counts as a discard. You don’t need to discard any additional starter. My friend works at a bakery and she says they never discard starter – they’re constantly using it.
How to use your gluten free sourdough discard
‘Discard’ to me has always implied that it’s an inedible waste product, destined for the bin. I think it’s incredibly important to point out that this isn’t the case! This is particularly relevant in gluten free sourdough baking – gluten free flour isn’t cheap.
The discard is essentially just starter that you’re not using. It is the same makeup as the starter you’re going to put in bread. So, why not put it in something else bready? Sourdough starter crackers, pancakes or brownies are all good places to start. You’d also be surprised by how many people would be interested in having some of your discard to make their own starter. Why not offer it to friends or family?
So yeah, I really just think it’s important to make the connection that discarding needn’t mean throwing in the bin. It simply means removing from the starter jar itself. If you’re baking and using your starter very often, you probably won’t need to discard anything. Each use of the starter counts as a discard, as you’re removing some and adding fresh flour to re-feed.
How long does it take for a gluten free sourdough to be ready for baking?
As we will go into in the in depth section, the point at which you’ll see some action is dependent on many things. These include climate, water quality, flours, luck, and everything in between. Generally speaking, you might begin to see some bubbles around day 2 or 3. Keeping your starter in a decent sized glass jar is helpful, as you can see the bubbles around the edges. It is also a great idea to use a rubber band or tape to keep track of where the starter sits in the container. This is because the starter will eventually start to grow, and having a measure is a great way of seeing overnight progress.
Knowing when your starter is ready to bake bread is an art that I probably haven’t mastered. In regular sourdough baking, you can drop a little starter in a glass of water, and see if it floats. Floating indicates that the starter carries enough gas to raise a loaf of bread. I haven’t had any luck doing the float test with any of my bubbliest starters – they simply disintegrate into the water. I suspect that it may not work for gluten free sourdough starters, because they don’t have the strength of gluten to hold them together.
If all has gone well, your starter is probably ready around the 7-10 day mark. This will be a speedier process in summer and a slower one in winter. When you stir it, it should feel thick with air and bubbles. You should hear a pop rock kind of sound, as the little gas bubbles are shuffled.
An important note: most sourdough websites suggest that you probably won’t get an amazing loaf of bread until your starter is at least a month old. If you’re getting average loaves with a new starter – be patient.
How to maintain your gluten free sourdough starter
Once your starter is bubbly and ready to roll, you need to keep it that way. To do so, you have a few options. Firstly, if you’re baking often, you can keep it on the counter, and continue feeding and discarding as you have been.
Secondly, if you’re only baking a loaf every week or so, you can store your starter in the fridge. This will slow fermentation considerably, meaning that you will only need to feed your starter around once a week. No point feeding and discarding a starter every day that isn’t being put to use. If you go down this road, make sure you bring your starter to room temperature a day or two before using. It will need to be fed at least twice, but there is no hard and fast rule for this – you need to pay attention to your starter and make sure it’s ready to make bread. This Youtube from Tartine’s founder was very helpful for me. It is not a gluten free starter or bread, but helpful nonetheless.
Finally, you can actually spread your starter into a thin layer on baking paper and dry it out. Once it’s dry, snap it into pieces and place it in an airtight container. When you want to use it, rehydrate it, feed it, and wait until it becomes it’s normal, bubbly self before using. This site is extremely helpful (although ignore anything that daunts you!)
Things to consider when making a gluten free sourdough starter
There are a few considerations to take in when starting up a gluten free sourdough starter. Don’t be frightened by them, but do pay a little attention to them.
Climate and kitchen
My experiments with gluten free sourdough began in Australian winter, and have continued through to our sweltering summer. As a result, I have experienced first hand the affects of the climate on sourdough starters. Making a starter in winter tends to take a lot longer than making one in summer. This can be cause for panic as a newbie. But fear not (within reason!) Be patient, be reasonably accurate, and be a good starter parent. You’ll be fine. The culture in your starter thrives and grows faster in warm temperatures, which is why it will take longer in cool climates.
In summer, you might notice that you have quite a bubbly sourdough starter in the first couple of days. That’s great! Continue feeding as usual until day 6 or 7 anyway, just to make sure you have a strong starter. You also need to have enough starter for bread.
In winter, this process can take a lot longer. It might take 10-12 days. You can lend a helping hand by giving your starter some warmth and a bit of honey or maple syrup. The warmth will help speed up the fermentation process. The sweetener will give the cultures something to feed on and do the same.
If you have the option, a few hours in the oven with JUST THE LIGHT on will do wonders for the fermentation. Just make sure you leave a note on the oven to remind yourself (and others) that it’s in there.
I have trialled a couple of different gluten free flours for my starter. The number one recommendation on the internet is brown rice flour, which was the first flour I tried. Don’t get me wrong, it definitely ended up doing the job. However, I felt that oftentimes it created more of a watery sludge that was slow to ferment.
In another attempt at making a gluten free sourdough starter, I used exclusively quinoa flour. I had read somewhere (backed up here, although the sourdough lingo is a bit above my pay grade) that starters benefit from a high protein flour, as it feeds the yeast nicely. I ground quinoa grains into a flour in my Nutribullet. This saved money and enabled me to create the quantity of flour I needed. Starters are hungry critters!
This time around, I have been using half quinoa flour and half sorghum flour. Sorghum flour can be found at health food stores. Personally, I have found that combination creates a fantastically bubbly sourdough starter that rises really well in the jar, more so than my original starter did. It is a cold winter here, so the fact that my starter was bubbly on day 3 or so is testament to this flour combo.
Whichever flour you use, I would highly suggest following a few of the basic flour storage suggestions in my gluten free flour guide. Namely, if you happen to be in a warm climate and have ever seen a small moth flying in your kitchen, freezing your flour. I recently had the very unfortunate experience of having to throw out an entire, mature quinoa flour starter. Why? Because it started sprouting weevils. A sight I will never forget.
Most sourdough starter tutorials suggest that you will need filtered or bottled water to create a sourdough starter. This is because tap water in urban areas often contains additives that can have an adverse effect on the growth of natural yeast.
Personally, I didn’t notice a difference between bottled and tap water. I hate using unnecessary plastic bottles. I found that my starter using tap water here in Melbourne wasn’t adversely effected at all, so I’ll continue down that path. That said, I began my starter experiments using bottled water, so if you’re feeling cautious or if the water isn’t great where you live, you can definitely use bottled or filtered.
Vessel of choice
Sourdough starter needs to be made in a glass jar or bowl, because it doesn’t play well with metal. A lot of people also suggest you use a wooden spoon to stir your starter, although I had forgotten this instruction until I was writing this post, and my starters have been fine with a metal spoon. As with most aspects of sourdough starter, I’d suggest starting cautiously (with a wooden spoon) and then doing whatever suits you best as you become more comfortable with the process.
If you are using a glass jar, make sure it is well cleaned and sterilised before use. Here are some instructions on how to sterilise a glass jar. This will ensure that there are no germs or general bits and bobs lurking around from the previous use that may negatively impact your starter. Make sure not to put any jar in the oven with any form of plastic attached to it.
I currently use a measuring jug which I keep in a ziploc bag. Clear vessels are great because I can see the bubbles easily, and know my starter is in good shape. I like using a ziploc bag because it gives my starter space to breathe without anything getting into it.
On that note: your sourdough starter should be covered. Most people suggest muslin cloth or something that will allow air to get in and circulate.
Gluten free sourdough starter questions and answers
Which gluten free flours can I use to create a sourdough starter?
I have used white rice flour, brown rice flour and quinoa flour.
At the moment my starter is mature and I have transitioned to a 100% fine white rice flour feed. I find it’s working well, and it’s a nice neutral base to bake different styles of bread from. It’s also inexpensive and easy to find. You can experiment with what works for you, and transition your starter however you see fit. I would definitely suggest the quinoa and sorghum combination to begin a starter, after which the world is your oyster.
The one flour I do not recommend is buckwheat flour. It feeds a starter incredibly well and looks the most like a wheat starter, but it has major drawbacks. For whatever reason, buckwheat starters seem to go mouldy at a much quicker rate than regular gluten free ones. I had a lot of close calls using buckwheat so I do not recommend it.
Can I use a gluten free flour blend for my starter?
I would not recommend. Gluten free flour blends have additives such as gums and baking powder added. I haven’t even bothered to Google this to know it’s not a great idea. If you buy flour at a bulk store, it is FAR cheaper and you’re not wasting your blend. I’m biased against gluten free flour mixes in the first place, but this seems like a terrible idea.
Another bad idea? Using a starch like tapioca flour or potato flour. Apparently the yeast will feed too quickly which can cause problems with your starter. A gluten free, wholegrain flour is best.
Can I mix up the flours that I feed my starter with?
Yes! Please do! But within reason. While I wouldn’t necessarily recommend feeding the starter with a different gluten free flour every day, you can use different flours if you run out of your original flour. You can also combine two flours, like I do with sorghum and quinoa. Apparently, after a while, your sourdough will eat away the remnants of the old flour you were using without a trace. So, for example, if you were to start feeding your quinoa flour starter brown rice flour, it would eventually become an entirely brown rice flour starter.
A caveat: starters do like consistency. Both in their feed and discard schedule, and in their feed itself. While you can move your starter to a different feed if you need to (better than not feeding it at all) for best results, don’t be too flippant.
Another caveat: starters do not like starches. Think tapioca flour, potato starch or cornflour.
Why do I need to discard starter?
Put simply, discard assists in keeping the starter healthy and small. It also (more importantly) bakes a better bread.
As the sourdough starter grows, it produces waste products (don’t we all?) that remain in the starter. Discarding starter removes some fermentation waste byproduct. It replenishes the starter with fresh food to become stronger. Here is a better explanation than I could ever muster.
Another more simple reason discarding is that if you don’t, your starter will soon become an unmanageable monster that requires vast amounts of flour to feed. The bigger the starter gets, the more flour it needs. Discarding assists in keeping a starter small and healthy.
What can I do with all the leftover starter I have?
Make and eat a lot of bread? Just kidding. Kind of, but not really at all. If you have a lot of sourdough starter, you have a lot of options. Instead of discarding overflowing starter, try using it in pizza bases, loaves, waffles – basically anything that needs rising, or could benefit from the wonderful tang of sourdough. If you’re not that into baked goods? Dry the excess sourdough out and give it to friends. Find a local Facebook group and ask if anyone wants from sourdough starter. I can guarantee someone will take you up on it.
If your starter is getting to an overwhelming size, consider that you either need to start baking or put the starter in the fridge. Excessive size suggests that you’re feeding the live starter, but not actually doing anything with it. No point feeding something you’re not using, so see the point above on how to store your starter.
Can I go on holidays or am I forever beholden to my starter?
Great news! You can actually leave your starter, and you have a few options for doing so. Firstly, you can refrigerate your starter for up to a week. This is often what people do if they don’t need the starter that often – keep it in the fridge, and feed it once a week. The night before you are using it, simply feed it, and bring it back to room temperature on the bench. It should be good to go by the next day.
Dare I say that on my recent trip to the USA, I left my starter in the fridge for 3 weeks and it survived without issue. I simply overfed it before I left and crossed my fingers. It took about a week of daily feeding to return to it’s former glory, but it worked!
Secondly, you can overfeed your starter with flour (give it double or triple what you normally would, but only a little water) and leave it in the fridge for the duration of your trip. I personally haven’t tried this method, but given the resilience of most of my starters, I can see how this would work well.
Thirdly, you can thinly spread your starter on a baking sheet or silpat, and allow it to dry out completely. From there, break it into pieces, and store it in an airtight container. When you next want to use it, rehydrate it and feed it, continuing to do so until it returns to it’s original bubbly form.
What are the differences between a gluten free starter and a regular starter?
As someone who has never made regular sourdough, and who has spent her whole baking career using gluten free flour, this is hard to answer. But imma try anyway.
While researching my first starter, I compared a lot of regular sourdough recipes to gluten free recipes. I found a few differences. Firstly, it would seem that regular starters are more prolific than gluten free ones, because many blog posts speak of discarding half the starter every day. That, to me, would indicate that they grow quite rapidly. I haven’t found this with my gluten free starter – it doesn’t grow exponentially every day.
In that vein, regular starters seem to give a lot more rise to bread, which means that gluten free sourdoughs will always look quite little and sad in comparison. Manage your expectations is the takeaway message here. You probably won’t (I haven’t) achieved those beautiful giant air bubbles in your loaf. That’s ok. It will still be that delicious, tangy bread you know and love.
People speak of dropping their regular sourdough starter in water to see if it floats – this has never worked for me with gluten free starter, even a very active one. I am currently unsure if this is something to do with my starter, or whether this just doesn’t happen for gluten free varieties. When I know more, you’ll know more.
Finally: gluten. Glutinous sourdough starters will always contain a lil bit of gluten. The gluten isn’t completely broken down. Have a read of this article from Bon Appetit, about sourdough and FODMAPs. I’d recommend keeping the starter gluten free if you are coeliac, and personally I like to keep it gluten free too.
Gluten free sourdough starter troubleshooting
Why isn’t my starter growing?
There are a few considerations to make when addressing this situation. First, how long has the starter been going? If it’s a new starter, and you’re in a cold climate, relax and give it time. You might want to up the feeding schedule a little bit to make sure your starter is getting enough food to grow.
However, if you’ve given the starter a very reasonable amount of time to grow (10+ days) and fed it consistently, it might be time to admit defeat. There is a fine balance between reviving a starter and wasting flour. Sometimes starters really do just fail to take off. It has happened to me more than once.
Why does my starter smell like eggs? Why does my starter smell like nail polish remover?
On eggs: Depending on how old your starter is, this is a good thing! If it is in it’s formative stages, a rotten egg or sulphuric smell is totally normal. When the starter has matured, however, you should have a pretty distinctive ‘sourdough’ smell. Give it time but also trust your gut – if you smell something totally out of the ordinary or rancid after about 5 days, consider starting afresh.
On nail polish remover: this is also normal, although less of a good thing. My research indicates that this means you’re starter is hungry, so you will need to up the feeding schedule a little. I feed mine around 75g flour and water instead of 50g if I get the nail polish smell.
How can I tell if my starter is active?
Active starters generally have a strong smell and have plenty of bubbles. You should be able to hear bubbles popping as you stir the starter, and it should pour out of the jar as bubbly sludge. As mentioned earlier, be sure to give your sourdough starter some time before panicking, particularly in winter or cold climates.
What do I do if there’s pink or orange mould on my starter?
Mould itself (which can be caused by any number of factors) is no cause for alarm. You can scoop it cleanly off, and continue as normal. However, pink or orange mould is apparently cause for concern and for you to discard said sourdough starter. This is because the starter has apparently lost it’s ability to fight off nasties, and it might be harbouring some within. Better safe than sorry.
If you want to dive really deep (too deep for me) into prevention of these types of issues, I stumbled across this pineapple juice method here. Worth a look, if you’re into research and very into sourdough, but not very into failing.
Why is the liquid on top of my starter brown/grey/murky?
According to Google any colour of liquid on the surface (or hooch, as it’s known in the starter world) is fine. You can stir it back into your starter, and give it a little extra food and love. You can also pour it off the top of your starter, and feed as usual. If you have persistent hooch, that might be a sign that your sourdough needs more food than you are currently giving it. Time to up your feed amounts.
Why does my starter smell like alcohol?
This is a normal part of the sourdough process. It should progress through this stage, and onto a stage of smelling yeasty, floral and generally like sourdough in the next couple of days. If it persists in smelling like alcohol, try feeding it more, or in more regular intervals. See the point on nail polish remover smells.
Why is there a skin on top of my starter?
I dealt with this a lot during my early sourdough starter making, and apparently it is because there is too much air reaching your starter. The skin can very easily be peeled off and discarded without any adverse affects on the starter, but consider transferring your starter to a vessel with a smaller opening, or with a lid, or both.
These days, I use a large measuring jug or a ceramic vessel with a jumbo ziplock bag that I reuse. This seems to be a good balance between giving the starter air but not allowing it to form a skin or let any nasties in.
More notes and instructions
A recipe plugin is not the place for verbose instructions on sourdough, so I thought I’d discuss a feeding schedule here. This is a loose idea of what to expect on which day. I say loose, because climate, water, flours, and luck all have a lot to do with the speed at which your starter will progress.
DAY 1 – 5 (or up to 7-10, depending on your starter)
Begin your starter by adding 50g flour and 50g water to a clean glass vessel of choice. My recipe asks for 25g of quinoa and sorghum flours, but you can mix this up and experiment as you see fit. You can use all one variety of flour (i.e 100% quinoa or 100% brown rice flour) but as with most gluten free baking, I find a mix to work better.
Feed your new starter this flour and water combo, 2 times a day, roughly at the same time each day. Always stir to incorporate and add more water (to make that paste consistency) as you see fit. A new starter is more vulnerable, so do try and make sure you stick to this for the first week if you can.
Depending on the weather (starters are more prolific in warm temperatures) you should start to see some bubbles and activity within the 2-5 day mark. Don’t stress if you don’t – keep feeding it regularly and keep your eyes peeled. You may also experience a strong vinegar tang, a rotten egg smell, or just a general unpleasant odour. Persevere past this and continue feeding – this is normal and it will dissipate. I promise!
Even if your starter is bubbly on day two, continue the feeding schedule until day 5-7. It needs to be mature before you use it, and you also need enough volume to not use the entire starter up when you bake bread.
By day 5, there should be lots of bubbles and they should pop when you stir the starter. It should be a living sludge. It should smell like a strong loaf of sourdough. There should be no liquid on the top – feed it well before using it if there is.
Personally, I like to wait until around day 7 to start using my starter. I want to give it the best chance possible.
A note on hydration
100% hydration starter is a little more complicated in gluten free sourdough than it is in regular. Gluten free flours are often incredibly thirsty, meaning they’ll need a lot more water than regular flour. Your starter needs to be the consistency of a thick paste in order to ferment. It can be wetter, but it can’t be drier. So please take the 100% hydration as a guide. If your mixture is dry, add more water. Use a bit of intuition, and give your starter the liquid it deserves!
This might mean that your hydration 100% is not as precise as it could be, and that’s fine. I was never a maths person anyway.
Maintaining your starter
Congratulations! You’ve persevered through the most unpleasant stages of making a gluten free sourdough starter. Your starter should now be a bubbly, thick paste and it should smell like sourdough. To maintain it, feed it once a day as usual. Keep an eye on any hooch/vinegar smells and up the feeding quantity if these arise. Once you get in the groove, you’ll realise that you can often feed your starter by intuition. If it’s looking runny, I add flour but no water. Looking thick? Add a little extra water.
If you don’t plan to use your starter for the week, see the instructions about keeping it in the fridge. On that note, make sure your starter is well fed and at room temperature before you use it, so it is nice and active. Much like me before breakfast, you cannot ask a starter for a stellar performance while it is hungry.
Finally, a note of common sense: make sure you have enough starter to bake a loaf AND keep the starter going. If you use up your entire starter in a loaf, you will have to start from scratch again.
Gluten free sourdough resources
To be honest, the best learning is by doing. However, here are some handy resources for making your own starter.
- A good video on the general gist of making a starter. There’s no mentions of discard but if you’re a visual learner, this might help.
- I have a gluten free sourdough recipe here, and a white bread gluten free sourdough recipe here.
- There is a sourdough website which is basically a chat forum of all things sourdough. If you have ever googled something sourdough related, chances are you ended up there.
- Not gluten free, but The Perfect Loaf has a great sourdough guide, and is an insane sourdough baker and specialist. I am a crazed Instagram fan.
Final tips for your gluten free sourdough starter
- Don’t get bogged down percentages and fancy French terms and feeding schedules. Feed it twice a day with flour and water. Experiment and have fun! Personally I think the process is much more intuitive than people on the internet make it sound. My loaves are definitely not as good as theirs, but that’s fine! The bread is still 10,000 times better than the supermarket variety, and better for me to boot.
- Buy flours in bulk from a bulk food store. You will go through a lot of flour in this process, and that’s way too much packaging to go to landfill. Make sure you store your flours correctly.
- Starters are more prolific in summer and take a lot longer in winter. Be patient.
- Don’t bin your starter at the first sign of a weird smell or a dark liquid. We’re fermenting!
- If all else fails, make it up as you go along. That’s what I did when I started, and I learnt a whole heap on the way.
- I have written a detailed account of what to expect below the recipe card.

Gluten free sourdough starter
- Large glass jar with a lid
- Muslin cloth, to keep bugs out when 'airing' the starter
- A wooden spoon, or anything that isn't steel
- Kitchen scales, for weighing out the feeds
- An elastic band or tape, to measure starter growth (the funnest part!)
- 25g quinoa flour (see notes on flour)
- 25g sorghum flour (or another wholegrain gluten free flour, like brown rice flour)
- 50g water (see notes on water)
- Combine your water and flour in a sterile glass jar or clean glass bowl. Ideally, you'd do this in the morning, and then feed the starter the same amount again in the evening. If your starter is not the consistency of a thick paste, add more water. It should not have a dry, crackly top – add a little extra water if it does.
- Continue this pattern of feeding until the starter begins to bubble, and become active. It should be roughly the consistency of a thick pancake batter. After 2 or 3 days, or when there are considerable bubbles on the starter, discard around half of the starter (see intro on what to use discard for) and feed the starter as per usual. Discard once a day for optimal results.
- To keep your starter alive, continue to feed it once or twice a day, with the same 50g flour and water measurements. Stir well to incorporate after each feed. The starter should look like a thick paste but without a dry crackly top – you can add more water to achieve this consistency if necessary. Every gluten free flour is different (including each bag) so I often eyeball how much water I add. Discard or use starter every couple of days, and feed after each discard. Most gluten free bread recipes I have seen ask for 1 cup of sourdough starter per loaf, so make sure you have enough to make a loaf and also keep the starter going.
- To store the starter, see notes and links in the introduction.
- Make sure the starter is fed and in it's peak 'rise' before you use it to make sourdough. See the links in the resources section for more information.
- After every use (discard or sourdough) feed your starter straight away to replenish what has been taken. Always ensure you have more than enough starter for a bake, otherwise you'll have to begin the process again.
