proof means: 1. To prove that yeast is alive, dissolve it in warm water. Leave it to rest in a warm area for five to ten minutes. It is considered alive if it bubbles up and expands.

What else does proof mean?

This term refers to the time that a bread product has been allowed to rise before it’s shaped, baked and put in its pans. Products should be proofed up to twice their size or until a light finger placed lightly on one side of the loaf leaves an indentation. The product is “proofed” at 950F to 1000F in an airy, draft-free area. To prevent crust drying, you can lightly place a slightly dampened, non-terry, cloth towel, or plastic wrap, spray with pan spray, over the product. Some ovens include a proofing function. Refer to the instructions provided by your manufacturer. (in Cooking Dictionary)
