ALL-PURPOSE FLOUR-CAKE FLOUR vs SELF-RISING FLOUR
All-purpose flour is plain flour and when a recipe calls for flour this is what they mean.
Self-rising flour is AP flour with baking powder and salt added to act as a leavening agent (meaning, to help your baked goods rise). To make your own, the recipe is as follows:
1 cup all-purpose flour + 1 teaspoon baking powder + 1/4 teaspoon salt = 1 cup self-rising flour.
Can I substitute one for the other? No. Just buy AP flour and add baking powder if a recipe ever calls for self-rising flour and you can’t find it.
