All-Purpose Flour Measuring FAQs

Why does 1 cup of all-purpose flour vary from 120g to 145g? ▾

Dipping the cup straight into the bag compacts the tiny particles, packing up to 25% more flour than gently spooning and leveling.

Can I swap all-purpose flour for bread flour by weight? ▾

Yes, substitute 100g of bread flour for 100g of AP flour, but note bread flour absorbs slightly more water due to higher protein.
