A high-protein white flour for bread, rolls, pizza and puff pastry, milled from wheats selected for their bread making qualities. Four-time Great Taste Award winner.
For sourdough
At 13.3% protein this is a dependable everyday white flour, and at 1.5kg it is the cheapest per kilo of the whites we stock. Good for the loaf you bake every week and for feeding a starter in volume.
It is not organic. If that matters to you, the organic strong white is the same sort of flour with Organic Food Federation certification. For a wetter dough and a more open crumb, the Matthews 100% Canadian at 14.5% holds more water.
Folic acid
This flour is fortified with folic acid, which UK law requires in most white wheat flour. If you would rather bake without it, the regenerative stoneground strong white is the closest white flour with none added, or see all our flour with no added folic acid.
