While you’re waiting for the pumpkin, place the almond meal, tapioca flour, finely grated parmesan and salt in a large mixing bowl. Stir to combine.
Pour the melted butter into the mixture and use a spoon to combine. It should have the appearance of wet sand.
Add the eggs and mix well. It should come into a smooth-ish ball of dough. If it looks dry, add a splash of milk or water. If it’s too sticky to handle, put it in the fridge to firm up for 10-15 minutes. Make sure you weigh the flours for the best results.
When you’re ready, press the dough into a 24cm fluted tart tin. You don’t want it to be too thick so remove any excess dough (you can bake it into cheese biscuits).
Poke plenty of fork holes in the base and set the tin on a baking tray (this makes it easier to remove from the oven). Place the tart pastry into the oven for 20-25 minutes, or until it is nicely browned.
Once the tart base is ready, brush it with a bit of the whisked egg you'll use for the ricotta. Allow it to cook for 3-5 minutes more. This ensures that the crust base doesn't become soggy - it forms a barrier between the wet ricotta and the crust.
Remove the tart pastry from the oven and allow it to cool a little while you prepare the tart filling.
