Soaking potatoes in cold water removes excess surface starch, leading to crispier fried/roasted potatoes, creamier mashed potatoes, prevents sticking, and stops them from turning brown (oxidizing) before cooking. The cold water helps the starch cells close, resulting in a better texture and more even cooking by removing the gummy substance that makes potatoes sticky.
