Proofing bread in a basket gives support to an expanding loaf and helps it maintain its shape. When the basket is a brotform, it also imprints the crust with a beautiful spiral pattern that lends the finished loaf a rustic European flair.
A brotform (German for “bread mold” – see why we stick with the German name?) is a coiled cane basket that holds the shaped dough during its final proof. My brotforms (or brotformen, if you want to keep strictly to the German) are round and oval, but they also come in rectangular, square, triangular, and a variety of other shapes. A 7.5- or 8-inch diameter round brotform is a good size for up to a 1.5-pound loaf.
