A pastry board is a flat, smooth surface used for rolling out dough and preparing pastries. Typically made from wood, marble, or plastic, it provides a clean area for working with various types of dough, such as pie crusts or cookie dough. The board's surface helps prevent sticking, making it easier to shape and cut the dough. Pastry boards often come in different sizes and can be used in both home kitchens and professional bakeries. Some boards may have measurements or guides printed on them to assist with rolling out dough to the desired thickness, ensuring consistent results in baking.
