About measuring cake flour
Cake flour is milled finer and lower in protein than all-purpose flour, which is what gives sponges and layer cakes their tender, delicate crumb. One US cup weighs about 120 grams, a little less than all-purpose because the flour is so soft and light. It clumps readily, so sifting before measuring makes a real difference. If a recipe calls for cake flour and you only have all-purpose, weigh out the grams and remove a spoonful or two per cup, then add a little cornstarch.
Sift cake flour before measuring. It clumps easily and a packed cup throws off tender bakes.
