Wheat flour

Wheat flour is the most common flour used in baking. There are different types of wheat flour, and they're distinguished by the amount of gluten they contain.

Gluten is the wheat's natural protein, and it's what gives baked goods their structure. When the dough is kneaded, these glutens develop and become elastic. Flours made from hard, high-protein varieties of wheat are called strong flours. They have a higher gluten content. Flours made from softer, low-protein wheat are called weak flours and are lower in gluten.
