1largebunch of basil (or two small bunches, see notes)
100gfreshly grated good quality parmesan (see notes)
1cupwalnuts (110g) or pine nuts (150g)
60-125ml(1/4 - 1/2 cup)*good quality olive oil (see notes)
Juice of 1 lemon, to taste
Seasoning, to taste
Instructions
Place all ingredients in the food processor and process until your desired consistency has been reached. Adjust for seasoning and lemon juice.
Store in an airtight container in the fridge and use within a few days.
Notes
1 cup of walnuts is generally around 110g and a FODMAP friendly serve of walnuts is 30g. This means that this pesto only needs to serve 4, which is a very generous serving.
1 cup of pine nuts is around 140-150g in Australia, and a low FODMAP serve of pine nuts is 14g. This means that a pesto using pine nuts would need to make 10-11 serves. Not impossible, but a lot less generous than a walnut version.
Using garlic infused olive oil is a great way to add some classic garlic flavour. See my recipe for a homemade version here.
