Baker's supply is a term used to describe the items necessary for baking. This includes eggs, which are a key ingredient in many baked goods; seeds, which can be used as a topping or an ingredient; ovenware, which is necessary for baking in an oven; LARD, which is a type of fat used in baking; and YEAST, which is used to make dough rise. All of these items are essential for baking and are typically found in a baker's supply.
