All-Purpose Flour with Vital Wheat Gluten (Best Option)
1 cup all-purpose flour + 1 tablespoon vital wheat gluten per 1 cup bread flourBread flour typically contains 12-14% protein, which is essential for gluten development that gives scones their structure and chew. All-purpose flour has lower protein (around 10-11%), so adding vital wheat gluten boosts the protein content to approximate bread flour. This combination ensures the dough can trap steam and expand properly during baking.
To succeed, thoroughly mix the vital wheat gluten into the all-purpose flour before combining with wet ingredients to ensure even distribution. Avoid overmixing the dough to prevent toughness.
Compared to using bread flour directly, scones made with this substitute will have very similar texture and rise, maintaining the characteristic slightly chewy crumb and flaky layers.
