Substitute by weight, not volume. Moreover, because they are finer, they weigh less than all-purpose flour, so it is a good idea to substitute your blend for the all-purpose by weight, rather than by volume. If the original recipe calls for 260 grams of all-purpose flour, substitute with 260 grams of your blend. Hope that will help!
