I am looking for proportion to make self-rising flour. I know that is made from flour and baking powder.
According to joyofbaking.com add 7.5 grams baking powder and 3.5 grams salt per 140 grams of all-purpose flour.
To make one cup of self-rising flour:
* 1 cup of all-purpose flour
* 1 1/2 teaspoons of baking powder
* 1/2 teaspoon of salt
Note: Unless a recipe calls for self-rising flour and yeast specifically, do not use it in yeast dough recipes.
Found this on several sites and the recipe was identical.
