Baking needs include ovens, ovenware, leavens, and cakepans. Ovens are a necessary appliance for baking, as they provide the heat needed to cook food. Ovenware is the cookware used in an oven, such as baking sheets, pans, and dishes. Leavens are ingredients that are used to make dough rise, such as yeast, baking powder, and baking soda. Cakepans are the pans used to bake cakes, usually round or square with sides. All of these items are essential for baking.
