Bain-Marie. 'Mary's bath'. A water bath - a container of warm water in which smaller pot(s) rest to provide slow, even cooking, protecting the extremities from over colouring. Ideal for sauces and custards or for keeping food hot. This is apparently named after Moses' sister, Mary, who was a chemist or after the Virgin Mary.
