A pastry brush
or basting brush
is a tool used to spread oil or glaze on food. Traditional basting brushes are made of plastic fiber similar to paint brushes
, while modern pastry brushes are frequently made out of silicone
. In roasting meats, a basting brush will be used to sop up juices or drippings from under pan and spread them on the skin of the animal to crisp the skin. In baking breads
, a pastry brush is used to spread a glaze
on the crust or surface of the food.
