All-Purpose Flour with Vital Wheat Gluten (Best Option)
1 cup all-purpose flour + 1 tablespoon vital wheat gluten per cup of bread flourBread flour typically contains 12-14% protein, which is essential for gluten development that provides structure and chew in biscuits. All-purpose flour has about 10-11% protein, so adding vital wheat gluten increases the protein content to approximate bread flour. This helps create the gluten network necessary for proper rise and texture.
To succeed, thoroughly mix the vital wheat gluten into the all-purpose flour before combining with wet ingredients to ensure even gluten formation. Avoid overmixing the dough to prevent toughness.
Compared to using bread flour directly, this substitute yields biscuits with very similar texture and rise, preserving the desired flakiness and chewiness.
