How to Cut In Butter
When a recipe calls for cutting butter into a dry mixture, make sure the butter is cold. Slice the butter into tablespoon-size portions, then add to the dry mixture. Use a pastry blender or 2 knives to cut the cold butter into the dry ingredients. When the mixture resembles coarse crumbs, it has reached the proper consistency.
