Self-rising flour is a type of "soft" flour that contains added baking powder and salt. When speaking of flour, the term "soft" indicates a low-protein content.

According to Nathalie Dupree in "New Southern Cooking," soft flours, including self-rising flour, are traditional in the American South where lower-protein winter wheat predominates. Plain flour is also a low-protein flour that you can convert to self-rising.

Measure 1 level cup of plain flour into a mixing bowl. To measure accurately, spoon the flour into the measure and then level off the top using the straight edge of a butter knife or a wooden spatula.

Add 1 tsp of baking powder and 1/4 tsp salt to the flour.

Whisk together all the ingredients.
