What is self-rising flour?

Self-rising flour is all-purpose flour that has a leavening agent— baking powder— and salt added to it. I don’t often bake with it, but it is perfect for recipes like this where so little amounts of each ingredient are required.

If you don’t have self-rising flour, you can substitute 1 cup of self-rising flour with 1 cup all purpose flour, 1 tsp baking powder and 1/4 tsp salt.
