A pastry brush is a kitchen tool used primarily for applying liquids like melted butter, egg wash, or glaze to pastries and baked goods. It typically features a handle made of wood, plastic, or silicone, and bristles made from natural or synthetic materials. The brush helps achieve a golden-brown finish on items such as croissants and pies. In addition to pastries, a pastry brush can also be used for basting meats or greasing pans. Its design allows for even distribution of liquids, enhancing both the appearance and flavor of the food. Proper care, such as cleaning after use, can extend the life of a pastry brush.
