The four levers

Flatbreads are mostly controlled by four things: flour, water, leavening and fat. Heat and resting time matter too. Once you know what each one does, you can make most flatbreads without a recipe.

1. Flour: it's all about protein (gluten)

When wheat flour meets water and gets worked, its proteins form gluten, a stretchy network. More protein gives more gluten, which means more chew, more stretch and better gas-trapping. Less protein gives a softer, more tender result.

Flour Protein (approx) What it does Best for
Plain flour 9-11% Soft, tender, moderate stretch Paratha, quick naan, pitta at a push
Strong white bread flour 12-14% Chewy, elastic, holds gas well Pizza, pitta, chewier naan
Tipo 00 11-13% (pizza grade) Very finely milled, silky, absorbs less water Neapolitan-style pizza (nice, not essential)
Atta ~11-13% Wholewheat, very finely stone-ground Chapati, roti, paratha
Self-raising Plain flour + baking powder Built-in chemical lift Quick, no-yeast naan and flatbreads

Atta is not the same as UK wholemeal. Atta is ground very fine from hard wheat in a chakki mill. That milling damages the starch, so it soaks up more water and gives a soft, pliable dough that rolls thin. UK wholemeal is coarser, and a chapati made with it comes out heavier and more crumbly. If you're stuck without atta, mix roughly 50/50 wholemeal and plain, or sift the wholemeal.

Self-raising is just plain flour with baking powder already mixed in, about 1 tsp per 100-150g. You can make your own anytime.

2. Leavening: how (or whether) it rises

3. Water (hydration)

Bakers measure water as a percentage of flour weight. For example, 100g flour with 65g water is 65% hydration.

Atta is thirsty, so it needs more water than plain flour to reach the same softness. Liquids like milk and yoghurt count roughly as water but also tenderise the dough.

4. Fat, salt, sugar
