Keeping this in consideration, how do you keep scalloped potatoes from turning black?
If raw, once the potato is cut you can store in the refrigerator, covered with water for 12-24 hours. Be sure to keep submerged in water to prevent slices from turning gray or brown. Add a tablespoon of white wine vinegar or concentrated lemon juice to a gallon of water to help keep the potatoes from turning dark.
