I have baby bite-sized potatoes that peeling isn't necessary. Do I soak them to avoid them turning gray?

Peeling isn’t necessary for potatoes – baby or otherwise! It’s all a matter of personal preference if you like skin on, or off. Potatoes will only discolor if they are left exposed to air after peeling, or if kept too cold for too long, so never refrigerate potatoes. When peeling and cutting potatoes, place immediately into cold water with a little vinegar or with some citric acid (lemon/lime juice) 1 tablespoon per gallon to prevent discoloration.
