Gluten-free baking fails when you only remove things

This works through gluten-free baking in the order the parts actually depend on each other.

What you are actually replacing

Gluten does several jobs simultaneously: it stretches, it traps gas, and it sets into a network that holds the crumb. No single alternative flour does all three, which is why one-for-one swaps produce crumbly or gummy results. Commercial gluten-free blends combine flours, starches and binders precisely because the job needs several components.

Understanding this is the difference between adapting recipes hopefully and choosing recipes designed for the purpose.

Blends beat single flours

Rice flour is neutral but gritty, sorghum and millet bring flavour, and buckwheat is strongly flavoured despite the name. Starches such as tapioca, potato and maize give lightness and chew but no structure on their own. Ground nuts and pulse flours contribute protein and fat, which changes texture and browning.

On a weeknight, most successful blends use a base flour, a starch and something with protein, in proportions the recipe has tested.

Binders do the elastic work

Xanthan and guar gums provide viscosity and gas retention, which is the closest available substitute for elasticity. Psyllium husk holds a great deal of water and gives gluten-free bread doughs something to hold their shape with. Eggs contribute structure and lift, which is why many gluten-free cakes work better than gluten-free breads.

The part that matters: too much binder gives a slippery, gummy texture, and the useful quantities are small.

Hydration and resting

Gluten-free flours and starches absorb water at different rates, and many need more liquid than a wheat recipe would. Resting a batter for a period lets that absorption finish, which reduces grittiness noticeably in rice-based blends. Batters often look worryingly loose compared with wheat equivalents and are correct that way.

This is a case where following the recipe exactly matters more than usual, because the margins are narrower.

Expect different textures

Gluten-free bread rarely has the chew of wheat bread, and pretending otherwise leads to disappointment. It performs best in formats where structure matters less: flatbreads, pancakes, tarts, brownies and dense cakes. Staling is generally faster, so gluten-free baking is often better eaten fresh or frozen in slices.

Naturally gluten-free traditions, from polenta to rice-flour dumplings, are a better starting point than substitution.

If it is medical, contamination matters

For coeliac disease and similar conditions, trace contamination from shared equipment, flour dust and toasters is a genuine issue. Oats are frequently contaminated in processing unless specifically labelled, and some people react to them regardless.

Anyone avoiding gluten for medical reasons should follow the guidance of their own clinician and their national coeliac organisation. This article is about texture and technique, not about diagnosis or dietary management.

The takeaway

Use recipes designed for gluten-free flours rather than wheat recipes with the wheat taken out.

Taste it before it leaves the pan. That is most of cooking.
