Bain-marie
Encyclopedia
A bain-marie is a French
term for a piece of equipment used in science
, industry
, and cooking
to heat materials gently and gradually to fixed temperatures, or to keep materials warm over a period of time.
Typically the inner container is immersed about halfway into the working liquid.
The smaller container, filled with the substance to be heated, fits inside the outer container, filled with the working liquid (usually water), and the whole is heated at, or below, the base, causing the temperature of the materials in both containers to rise as needed. The insulating action of the water helps to keep contents of the inner pot from boiling or scorching.
When the working liquid is water and the bain-marie is used at sea level
, the maximum temperature of the material in the lower container will not exceed 100 degrees Celsius (the boiling point of water at sea level). Using different working liquids (oils, salt solutions, etc.) in the lower container will result in different maximum temperatures.
below both pots. The dry-heat form of electric bains-marie often consumes less energy, requires little cleaning, and can be heated more quickly than traditional versions. They can also operate at higher temperatures, and are often much less expensive than their traditional counterparts.
Electric bains-marie can also be wet, using either hot water or vapor, or steam, in the heating process. The open, bath-type bain-marie heats via a small, hot-water tub (or "bath"), and the vapour-type bain-marie heats with scalding-hot steam.

to heat materials gently and gradually to fixed temperatures, or to keep materials warm over a period of time.
Description
The bain-marie comes in a wide variety of shapes, sizes, and types, but traditionally is a wide, cylindrical, usually metal container made of three or four basic parts: a handle, an outer (or lower) container that holds the working liquid, an inner (or upper), smaller container that fits inside the outer one and which holds the material to be heated or cooked, and sometimes a base underneath. Under the outer container of the bain-marie (or built into its base) is a heat source.Typically the inner container is immersed about halfway into the working liquid.
The smaller container, filled with the substance to be heated, fits inside the outer container, filled with the working liquid (usually water), and the whole is heated at, or below, the base, causing the temperature of the materials in both containers to rise as needed. The insulating action of the water helps to keep contents of the inner pot from boiling or scorching.
