Like a bain-marie, a double broiler is a method of cooking without using direct heat. It usually consists of two saucepans that fit together. The bottom sauce pan is filled with water and the top one with the mixture (custard, chocolate, etc.). The saucepans can be made from stainless steel, aluminum, and glass.
