All-Purpose Flour with Vital Wheat Gluten (Best Option)
For every 1 cup bread flour, use 1 cup all-purpose flour plus 1 tablespoon vital wheat glutenBread flour typically contains 12-14% protein, which contributes to gluten development and the chewy, structured texture in waffles. All-purpose flour has lower protein (about 10-11%), so adding vital wheat gluten boosts the protein content to approximate bread flour.
To ensure success, thoroughly mix the vital wheat gluten into the all-purpose flour before combining with wet ingredients. Overmixing should still be avoided to prevent toughness.
The final waffles will have a texture and chew very close to those made with bread flour, preserving the characteristic crisp exterior and tender interior balance.
