What is "self-raising flour"?

Self-raising flour is a type of flour that has a leavening agent, such as baking powder, already mixed into it. This allows baked goods made with self-raising flour to rise during baking without the need for additional leavening agents like yeast or baking soda. Self-raising flour is commonly used in recipes where a light and airy texture is desired, such as cakes, muffins, scones, and quick breads. It is convenient for home bakers as it eliminates the need to measure and mix separate leavening agents, making baking quicker and easier. However, it is important to note that self-raising flour may not be suitable for all recipes.
