Why is it called 'Bain marie'

If you have ever been in a professional kitchen or watched cooking shows, you may have come across the term ‘Bain marie’ (pronounced as ban mah-REE). This technique, also known as a water bath, is commonly used in cooking and baking. But have you ever wondered why it’s called ‘Bain marie’? Let’s take a look at the history and origin of this culinary term.

The term ‘Bain marie’ has its roots in French and can be translated as ‘Mary’s bath.’ Surprisingly, it has nothing to do with any culinary icons named Mary. Instead, it is believed to have been named after Maria the Jewess, a renowned alchemist and inventor who lived in the first century Alexandria, Egypt. Maria the Jewess was one of the pioneers in developing various chemical and culinary techniques, and the invention of the water bath was attributed to her.

Throughout history, alchemists like Maria the Jewess sought to transform and combine different substances, and they recognized the need for a controlled heating method. The ‘Bain marie’ was invented to heat delicate materials such as oils, resins, and alchemical compounds without applying direct heat. This technique allowed for a gentle and consistent temperature, which was essential for preserving the desired qualities of the substance being heated.

Over time, the technique was adopted by cooks and bakers to address similar needs in the culinary world. The ‘Bain marie’ became a valuable tool in the kitchen for heating and melting ingredients that required low, even heat. Today, it is commonly used for making delicate sauces, melting chocolate, making custards, and cooking items like cheesecakes that demand a gentle and uniform heat distribution.

The ‘Bain marie’ consists of two key components: a container filled with water and a separate, smaller container placed within the water-filled one. The heat from the water surrounding the smaller container transfers slowly and evenly, preventing the direct application of heat that could risk curdling or scorching the ingredients being heated.

The scientific principle behind the ‘Bain marie’ is based on the fact that water has a higher specific heat capacity compared to air or direct heat sources. This means that water can absorb and distribute heat more efficiently and uniformly. By immersing the smaller container in hot water, the temperature of the ingredients can be carefully controlled, preventing unwanted changes such as burning or overheating.

Beyond its practical benefits, using a ‘Bain marie’ also offers a layer of insulation, which protects the delicate texture and flavor of the food being prepared. This technique ensures that the food is cooked gently and evenly, resulting in a smooth and consistent outcome.

So, the next time you come across the term ‘Bain marie’ in a recipe or a professional kitchen, you can appreciate its historical roots. Named after the ancient alchemist, Maria the Jewess, this culinary technique has stood the test of time. Its ability to provide controlled, gentle heat continues to be a valuable asset in modern cooking, ensuring the success of many delicate and delicious dishes.
