A Bain Marie works by surrounding the food with a gentle heat in order to warm dishes or carefully melt solids without burning them.  Moreover, you can also utilize this culinary must-have to store pre-cooked cuisines, such as chili, baked beans, or curry.  So, whether you’re prepping food for a buffet or catering a large event, having a few extra Bain Marie pots on hand is always a good idea.
