Proving Chamber

A dough proofer is a warming chamber used in baking that encourages fermentation of dough by yeast through warm temperatures and controlled humidity. It is also called a proofing box, proofing oven, or proofing cabinet.In bread baking, the word proofing most commonly refers to the final rise dough undergoes, which takes place after being shaped into a loaf, and before it is baked. In practice, however, the words proof and fermentation are sometimes used interchangeably.
