β Bread Flour (Best Dairy-Free Option)
1:1 (1 cup bread flour per 1 cup all-purpose flour)Bread flour contains 12-14% protein, higher than all-purpose flour, which promotes stronger gluten strands. This gluten network traps gas better during fermentation, yielding a light and airy crumb with a chewy crust typical of focaccia.
To succeed, ensure proper kneading to develop gluten fully and allow adequate fermentation time. Monitor hydration as bread flour may absorb slightly more water.
The final focaccia will have a slightly firmer bite and more pronounced chewiness compared to all-purpose flour, closely resembling traditional Italian focaccia texture.
