Sourdough Baking Tools
Match a proofing basket to your baking vessel
Compare the shape and working dimensions at every step, from proofing to the inside of the oven lid.
Start with the loaf shape
Choose a round basket for a round loaf and an oval basket for an elongated loaf. Then check the vessel you bake in. Its widest point may be above the base, so measure the floor where the dough actually sits.
Read dimensions at the right place
A basket's listed size may describe its top edge. A cast-iron vessel can advertise the outside size including its handles. Use the basket's working area and the pan's interior footprint when available, and keep any unlabelled measurement out of the fit calculation.
Plan the transfer
Before heating the vessel, dry-fit the sling or paper you plan to use and check the lid. Allow space for the dough you expect to load. If your regular loaf brushes the sides, compare a smaller basket or a vessel with a wider usable floor.
