1 cup rice flour, brown or white
1/2 cup potato starch, not potato flour
1/4 cup tapioca flour
2 tsp baking powder
1 tsp salt
1/4 cup oil
2 egg, optional (see notes)
1 1/2 cup buttermilk, or regular milk
1 tsp sugar
Mix all ingredients together with a whisk. If batter is too thick, add a bit more milk. If it’s too thin, add a little rice flour.
Cook in batches in a waffle maker.
Note: these can be made without eggs – just add a little more liquid to make up for them.
