Choose potatoes that are firm with a tight unblemished skin, having no sprouts or green areas. Store potatoes in a cool dark area. Don't refrigerate, as the cold temperatures will convert the starches into sugars, creating a mealy, dark potato. For other potato varieties, see boiling, new, red, sweet, white potatoes, and yams.
