Water & Steam

Scald

Heat milk just to the point before boiling to ready it for recipes

Scalding brings milk or cream up to just below a boil, until tiny bubbles ring the edge and a skin starts to form. It readies dairy for custards and doughs and was traditionally used to tame enzymes. Pull it the moment it steams and shivers — a full boil can scorch and curdle.

Scalding brings milk or cream up to just below a boil — around 77–82°C / 170–180°F, the point where tiny bubbles ring the edge of the pan and a thin skin begins to form — and then pulls it off the heat before it actually boils. It's a prep step rather than a finish: it readies dairy for custards, ice cream bases, breads, and cheese-making, helps dissolve sugar and bloom flavors like vanilla, speeds up recipes by warming the milk, and was traditionally used to deactivate enzymes (and, before pasteurization, to kill bacteria). The crucial cue is the timing: pull it the moment it steams and shivers, because a full boil can scorch the bottom and curdle the proteins.

Types & varieties

Plain scald

Heat milk to just under a boil to warm it for a recipe.

Infusing scald

Scald with vanilla, citrus zest, or spices, then steep to draw out flavor.

Tempering pair

Scalded milk is then whisked slowly into eggs to make a custard without scrambling.

How to do it

1
Use a heavy pan
A thick-bottomed saucepan heats evenly and resists the scorching that ruins scalded milk.
2
Heat gently and stir
Warm the milk over medium heat, stirring now and then so the bottom doesn't catch or the sugars scorch.
3
Watch for the edge bubbles
Tiny bubbles forming a ring around the rim and a faint skin on top mean it's reached scalding temperature.
4
Pull before the boil
Take it off the heat the moment it steams and shivers; a rolling boil scorches and can curdle the proteins.
5
Infuse or use
If flavoring, drop in vanilla or zest and let it steep off the heat; otherwise proceed with the recipe (temper into eggs slowly).

Why bakers and custard-makers scald

Scalding does a few useful things at once. It denatures a whey protein (beta-lactoglobulin) that otherwise weakens the structure of breads and the set of custards — which is why old bread recipes call for scalded milk for a softer, taller loaf. It speeds recipes by getting the milk hot before it's combined, and it dissolves sugar and extracts flavor from anything steeped in it, like vanilla beans. Historically, before pasteurization, scalding also killed bacteria and deactivated enzymes that would sour the milk or interfere with cheese-making. With today's pasteurized, homogenized milk, those enzyme-and-bacteria reasons are largely obsolete, so scalding is now mostly about speed, dissolving sugar, and infusing flavor (the protein benefit still applies, but matters less). Pulling it just under the boil matters because actually boiling milk drives off water, can scorch the lactose on the pan bottom, and may curdle the proteins.

Tips & pitfalls

Rinse the pan with cold water before adding milk — it helps prevent scorching on the bottom.
Stir occasionally and watch constantly; milk goes from scalded to boiled over in seconds.
If a skin forms and you don't want it, whisk it back in or strain before using.
Cool scalded milk slightly before whisking it into eggs so you temper instead of scramble them.
