Nigella prefers to use a combination of plain (all-purpose) flour and baking powder rather than self-raising (self-rising) flour for practical reasons. Self-raising flour contains baking powder but as baking powder will expire after a period of time you need to use up self-raising flour more quickly than plain flour.
Similarly, it is asked, what is difference between self raising flour and all purpose flour?
To substitute self-rising for all-purpose flour, look for recipes that use baking powder: about ½ teaspoon per cup of flour, minimum. Our self-rising flour includes both a concentrated form of baking powder, and salt. Add enough baking powder on your own to make up the difference.
Can you use self rising flour instead of all purpose flour?
Dear Jan: Self-rising flour contains salt and leavening (baking powder). If the recipe called for all-purpose flour, and all you had was self-rising flour, you could have used it by leaving out the salt and the baking powder that the recipe called for since it is already in the flour.
Can all purpose flour be substituted for self raising flour?
Self-rising flour is all-purpose flour with baking powder and salt added. To make your own, combine 1 cup of all-purpose flour with 1 1/2 teaspoons of baking powder and 1/2 teaspoon of salt.
