Learn how to mix butter, margarine or shortening into dry ingredients.
To work butter, margarine or shortening into dry ingredients. As you cut in the fat, it will begin to clump with the dry ingredients. Use a pastry blender, lifting it up and down with a rocking motion, until the particles are the desired size, usually coarse or fine crumbs or the size of a pea. If you don't have a pastry blender, hold a table knife in each hand and pull them through the ingredients in opposite directions, or use your fingertips, working quickly so the heat of your fingers doesn't soften the fat.
