Strong flour is wheat flour with relatively high protein content and strong gluten-forming potential. It is commonly used for bread, pizza dough, bagels and other products that need an elastic dough structure. Protein levels vary by mill and market; bread flour often falls around 12–14% protein, but the supplier’s specification should be checked.
Wheat flour contains gluten-forming proteins, mainly glutenin and gliadin. When hydrated and mixed, these proteins form a network that gives dough elasticity and the ability to retain fermentation gases. Strong flour generally supports greater gluten development than low-protein cake or pastry flour.
Example: use strong bread flour for a chewy bagel or an elastic pizza dough, while a low-protein flour is generally more suitable for a tender sponge cake.
Strong flour has higher protein and greater gluten-forming potential. Weak flour has lower protein and is often chosen for cakes, biscuits and shortcrust pastry where tenderness is desired.
French grades such as T45, T55 and T65 primarily describe ash content, not a universal protein classification. Some T55 or T65 flours are suitable for bread, but protein and baking performance vary by mill.
Chef’s tip: choose flour using protein content and the intended dough characteristics, not just the grade name or colour.
