Double boilers are a pair of nesting saucepans. When you bring a couple inches of water to almost a boil in the lower pan, then fit the two pans together, you can melt with the heat of the steam at a slow gentle temperature. Double boilers are ideal pans for melting chocolate, custards and any delicate mixture. Electric chocolate melting pots are a great option for melting batches of chocolate coating and candy melts. Candy melting pots will keep your coating melted for dipping treats.
