Self-rising flour

[Renato]

One of the first convenience mixes, self-rising flour is a blend of all-purpose flour, baking powder, and salt. When self-rising flour is used in a standard flour recipe, the baking powder and salt are then omitted. Approximate equivalent = 1 cup all-purpose flour, 1½ teaspoons baking powder, and ½ teaspoon salt.
