Bain-Marie
/ban mah-REE/also called water bath
A bain-marie, or water bath, is a gentle cooking setup where a container of food sits in or over hot water, so heat reaches it softly and evenly instead of directly. Bakers use it to bake cheesecakes without cracks, melt chocolate without seizing, and warm delicate egg mixtures without scrambling them.
What it is
The principle is indirect heat: water cannot get hotter than its boiling point, so anything surrounded by it is protected from the fierce, dry heat of an oven or a direct flame. In the oven, that means a cake tin standing in a tray of hot water; on the hob, a bowl resting over (not touching) barely simmering water. Either way, the water acts as a buffer that keeps the temperature low, even and steady.
Why it matters
Custard-based bakes like cheesecake are mostly egg and dairy, and eggs set gently or not at all — direct oven heat cooks the edges long before the centre, and the resulting tug is what cracks the top. A water bath lets the whole cheesecake set at the same unhurried pace, giving that dense, creamy, crack-free finish. The same gentleness saves chocolate: melted over water rather than a flame, it stays smooth and fluid instead of scorching or seizing into a grainy lump.
Common mistakes
Letting the water boil hard defeats the purpose — a bain-marie should barely shiver, not bubble furiously. When melting chocolate, an over-tall flame or a bowl touching the water can overheat it, and steam sneaking into the bowl will make chocolate seize; keep the bowl snug over the pan so no vapour creeps in. For oven baths, wrap a springform tin well or water will find its way into the crust.
At Love Made Edible
Our baked cheesecakes go into the oven standing in a water bath — it is the reason they come out with a smooth, level top and a texture that stays creamy right to the edge.

Frequently Asked Questions
Why are cheesecakes baked in a bain-marie?
Because cheesecake is essentially a baked custard. Direct oven heat sets the edges much faster than the centre, and that uneven pull is what splits the surface. Surrounded by hot water, the whole cake heats slowly and evenly, so it sets at one pace — creamy throughout, with no crack down the middle.
Can I make a bain-marie at home without special equipment?
Easily — it is a technique, not a gadget. For the oven, stand your tin in any deep roasting tray and pour hot water around it partway up the sides. For melting chocolate, rest a heatproof bowl over a pan of barely simmering water, making sure the bowl does not touch the water.
What is the difference between a bain-marie and a double boiler?
They are the same idea in different clothes. A double boiler is the stovetop version — a bowl or pot stacked over simmering water — usually for melting and warming. Bain-marie is the broader French term, and in baking it most often means the oven version, where a tin stands in a tray of hot water.
