How Long Can Peeled Potatoes Sit in Water?

Raw, peeled potatoes can sit in water overnight. It is a trick cooks use to prepare potatoes the night before for cooking the next day.

Covering potatoes with water prevents them from turning brown, which can be unsightly. The potatoes also need to be refrigerated to keep overnight. Martha Stewart suggests scrubbing the potatoes under cool water, and then peeling them.
