โญ All-Purpose Flour with Cornstarch (Best Dairy-Free Option)
For every 1 cup cake flour, use 1 cup all-purpose flour minus 2 tablespoons, plus 2 tablespoons cornstarchCake flour has lower protein (about 7-8%) compared to all-purpose flour (10-12%), which affects gluten formation. Adding cornstarch dilutes the protein content, softening the flour and reducing gluten strength, which is beneficial for bagels that require a balance of chewiness and tenderness.
To ensure success, sift the all-purpose flour and cornstarch together to evenly distribute the cornstarch. Watch dough hydration carefully, as the cornstarch can slightly affect absorption.
Compared to pure cake flour, this substitute produces bagels with a slightly firmer crust but a similarly tender interior, preserving the traditional bagel chew with a subtle softness.
