What not to use
Plain all-purpose flour with no added leavening: recipes written for self-rising flour have no other baking powder, so they won't rise.
Why the swaps work
Self-rising flour is lower-protein flour premixed with baking powder and salt, so recipes that use it skip separate leavening.
Questions people ask
Can I use all-purpose flour instead of self-rising?
Yes, if you add 1 1/2 tsp baking powder and 1/2 tsp salt per cup.
Do I need to change the recipe's salt?
The salt in the substitute replaces the salt built into self-rising flour, so don't add extra.
