Bread flour is high in gluten protein, with 12.5-14% protein compared to 10-12% protein in all-purpose flour. The increased protein binds to the flour to entrap carbon dioxide released by the yeast fermentation process, resulting in a stronger rise. Bread flour may be made with a hard spring wheat.
1 You can substitute bread flour for all-purpose flour cup for cup. 2  Just remember the texture will be more chewy than with all-purpose flour. 3  Cake Flour has the lowest protein content which is why it is most commonly used in cakes. 4  Cake flour produces the tender crumb we desire in cakes.
