Gluten does three things in baking: it builds structure, it traps gas so things rise, and it holds moisture. Take it out and you have to replace all three, which is why swapping in one bag of gluten-free flour usually gives something crumbly, gritty or oddly wet.
Blends work because different flours cover different jobs.
The three roles
Structure and flavour come from whole flours: brown rice, buckwheat, sorghum, oat, teff, chickpea. These carry protein and taste, but on their own they are heavy and often gritty.
Lightness comes from starches: tapioca, potato starch, cornflour. They give the soft, fine crumb people miss, and they brown well. On their own they are pure texture and no flavour.
Binding comes from a hydrocolloid: xanthan gum or psyllium husk. This is the part that stands in for gluten's stretch. Without it, bread crumbles and pastry will not hold.
A base blend
By weight: 40% wholegrain flour (brown rice or sorghum), 30% second flour for flavour (buckwheat, oat or almond), 30% starch (tapioca or potato). Then add binder: about 1% xanthan for cakes and biscuits, 2% for bread, or psyllium husk at roughly double that if you prefer it.
Mix a jar of the flour part and keep it ready. Add the binder per recipe, because bread and shortbread want very different amounts.
What each flour actually tastes like
- Brown rice: neutral, slightly sandy. The workhorse. Grind matters: finer is much better.
- Buckwheat: earthy and strong. Excellent in pancakes and dark breads, overwhelming above about a third of the blend.
- Sorghum: mild and soft. The friendliest wholegrain for cakes.
- Oat: sweet and comforting, good in biscuits. Buy certified gluten-free oats if it matters medically; ordinary oats are often cross-contaminated.
- Almond: rich and moist, no starch at all. Great in cakes, useless as the only flour in bread.
- Chickpea: savoury and assertive. Brilliant in flatbreads, wrong in a Victoria sponge.
Gluten-free dough behaves differently
Expect batters rather than doughs. Gluten-free bread mixture is closer to thick porridge than to something you knead, and that is correct: shape it with a wet spatula in a tin rather than trying to knead it into a boule.
It also needs more liquid, and it needs time. Let the mixture rest twenty to thirty minutes before baking so the flours and the psyllium fully hydrate. Skipping that rest is the difference between a moist loaf and a gritty one.
Bake longer and darker than you think. Gluten-free bakes hold more water and can look done while the middle is still wet; a probe reading around 96 to 98°C in the centre of a loaf is a better guide than colour.
Storage is the weak point
Without gluten, baked goods stale fast. Gluten-free bread is at its best on day one and is a toasting bread from day two. Slice and freeze the loaf on the day you bake it, and toast from frozen; that skips the sad middle days entirely.
Cross-contamination, if it is coeliac
If you are baking for someone with coeliac disease rather than a preference, the flour is only part of it. Shared toasters, wooden boards, flour dust in the air, a colander that had pasta in it: all of these matter. Use separate equipment and check labels on baking powder, oats and anything with "may contain".
This is general kitchen information, not medical advice. For diagnosis or a treatment plan, that is a conversation with a doctor or dietitian.
Start with what forgives
Brownies, flapjacks, pancakes, polenta cake and anything almond-based work well without much adjustment, because they were never relying on gluten for structure. Sandwich bread is the hardest thing in the category. Start at the easy end and the wins come faster.
