Self-raising flour has a magical sound to it. If you look at recipes that call for this type of flour, you will see that they do not require any additional salt or rising agents, though biscuits, cakes and breads made with seem to rise up just fine.
This is because self-raising flour already has a leavening agent called baking powder. Since the ingredients are evenly distributed throughout the flour, you will get the same nice lift to your baked goods every time you use it. This type of flour is ideal for fruit cakes and other sweets.
