I've noticed there are lots of recipies calling for Self Rising Flour. I make my own and it's every bit as good as the store bought and much, much more economical!
Self Rising Flour - Homemade:
For EACH CUP of Flour called for in the recipe, add
1/2 TBLS. Baking Powder
1/2 tsp. Salt
If your recipe calls for 4 cups of Self Rising Flour you would use 4 Cups All purpose flour plus 2 TBLS. Baking Powder and 1 tsp. Salt
