A pastry blender is used to make baked goods like pie crusts, biscuits and croissants. It is used with flaky baked goods that require butter to be cut into the flour mixture.
A pastry blender is a hand-held kitchen tool that allows butter to be cut into smaller pieces. To use the tool, add the required amounts of butter into the dough mixture. Hold the handle of the tool, and press the metal piece into the dough. Continue pressing down on the tool, watching as the metal lines of the tool break up the butter into smaller pieces. This is a simpler and less time-consuming way to cut butter for baked goods.
