A banneton is a type of basket used to provide structure for shaped loaves of bread during proofing. Banneton baskets are also known as Brotform or proofing baskets. It is normally used for doughs that are too soft or wet to maintain their shape while rising. Proofing baskets are distinct from loaf pans in that the bread is normally removed from these baskets before baking. Conventionally, these baskets are made out of wicker, but some modern proofing baskets are made out of silicone or plastic. A banneton will sometimes have a cloth liner to prevent dough from sticking to the sides of the basket. Bannetons become more non-stick with use as a small amount of flour accumulates in them. These baskets are used both to provide the loaf with shape and to wick moisture from the crust. Bannetons come in round or oblong shapes.
