Amaranth flour is very similar in texture to Coarse Cornmeal which is often used to make Polenta. Amaranth is naturally gluten-free and has a high starch content making it ideal to add some stickiness to other gluten-free flours.
Coconut flour is suitable for bread, cake, biscuit baking with a high fibre count and a natural self raising tendency. It does have a delicious coconut aroma but the flavour diffuses somewhat in the baking process.
Spelt flour is a relation of wheat. It has a light golden brown colour and a nutty flavour. It is easier to digest and higher in protein than wheat. It can be used for sweet and savoury cooking and baking and behaves similarly to a plain wheat flour.
Tapioca is a very fine, white, starchy flour which is used commonly in gluten free baking to help bind and raise cakes and breads. It has no flavour, so it can also be used similarly to potato flour or corn flour to thicken up soups, stews and sauces.
Tiger nuts are actually small tubers. When whole tiger nuts are ground down they make a naturally sweet flour, which makes an ideal addition to baking. Tigernut flour is high in fibre and is naturally free from gluten.
