Is there a substitute for self-rising flour?

Thank you!

Yes, you can make your own: mix together 1 cup all-purpose flour, 1 1/2 teaspoons baking powder, 1/2 teaspoon salt (some sources say 1/4 teaspoon salt, so it's up to you).

To sub self rising flour with all purpose flour: For each cup of all-purpose flour, add 1 1/4 teaspoons of baking powder and 1/4 teaspoon of salt.
