What Is the Difference Between All-Purpose, Bread, and Cake Flour?

Protein levels, gluten, and which flour to choose for different baked goods.

The main difference between flour types is protein content, which affects texture.
Bread flour has the most protein for chewiness, cake flour has the least for tenderness, and all-purpose flour falls in between for versatility.
Kitchen Tip: If you don't have cake flour, replace 2 tablespoons of each cup of all-purpose flour with cornstarch.
