All-Purpose Flour with Vital Wheat Gluten (Best Option)
1 cup all-purpose flour + 1 tablespoon vital wheat gluten per 1 cup bread flourAll-purpose flour typically has a protein content of 10-11%, lower than bread flour’s 12-14%. Adding vital wheat gluten increases the protein content, enhancing gluten network formation essential for doughnut dough elasticity and rise.
For best results, mix the vital wheat gluten thoroughly with the all-purpose flour before combining with wet ingredients. Watch hydration levels as gluten addition may slightly increase water absorption.
The final doughnuts will have a texture and chew similar to those made with bread flour, preserving the characteristic light yet chewy crumb and good structural integrity during frying.
