Scalding is a technique used in many recipes containing milk. To scald milk, you use a heavy bottomed pan or double boiler and bring the temperature of the milk to 85-100Â°C (185-212Â°F). At sea level, the milk should just start showing small bubbles and releasing steam at the lower end of this temperature range.
As the heating continues, the soft protein layer begins to dry out, which is why the milk forms a skin on the liquidâs surface. This layer of skin forms a hard barrier, causing steam to build up beneath it and increase the liquidâs temperature. When left alone, this often causes the milk to boil over.
