Flour

All-purpose flour is just that: good for all purposes, such as breads, cookies, and pancakes. A few recipes (such as the Biscuit Waffles) call for self-rising flour, which produces a particularly flaky biscuit. You can use all-purpose, cup for cup, in its place, plus 1 teaspoon baking powder and ¼ teaspoon salt per cup of flour.
