Gluten-Free Flour Library

Every gluten-free flour, starch and binder worth knowing — tested, compared, and explained for coeliacs. Every entry covers safety (cross-contact risk, what to look for on the label), how it behaves in real baking, and what to use when the bag runs empty.

The ten essentials

Compare them side by side

Absorbency, binding and lightness rated 1–5 from our test bakes. Higher absorbency = needs more liquid; higher binding = more structure; higher lightness = airier crumb.

Flour or starch — what’s the difference?

Flours (rice, buckwheat, almond, sorghum, chickpea, teff, oat) are ground whole grains, seeds or nuts — they bring flavour, nutrition and some structure. Starches (tapioca, corn, potato) are refined, near-pure carbohydrates — they bring lightness, chew and moisture, but no flavour. Nearly every good GF bake combines both: roughly 70% flour to 30% starch is the classic starting ratio.
