A proving drawer is an oven compartment or separate appliance with a limited temperature range that helps dough rise properly. In culinary terms, “proofing” or “proving” refers to the process of letting dough rise before it is baked. Some bakers use their warming drawer’s proofing function for their dough because it provides the gentle heat and draft-free area needed for a good rise. A proving drawer is essentially a drawer which can be heated to very low temperatures, typically ranging from 30ºC to 80ºC, and can be used to keep dishes warm until serving. It can also be used as a slow cooker. Proving drawers and warming drawers work in exactly the same way, and the terms are often used interchangeably.
While a proving drawer can be helpful for bakers, it is not necessary. Alternatives to a proving drawer include using the oven without turning it on, as the insulation of the oven provides the gentle heat needed for dough to rise. Some bakers also use their microwave or a warm spot in their kitchen, such as near a sunny window or on top of a warm appliance, to help their dough rise.
