*What is scalded milk?
Older recipes often call for scalded milk but it's not something you see as much anymore. This is a holdover from when milk wasn't universally pasteurized. So that biscuit recipe passed down from your great-aunt Annie might not need the scalding step for health reasons, anymore. At its most basic, scalding just means bringing milk to a temperature of 180°F and then letting it cool to 110°F (43°C). In the before-times, this helped to kill bacteria and an enzyme that prevented thickening in recipes. But now that milk is pasteurized, why do you need to bother? Scalding still serves a purpose when you add yeast, melt butter, or want to infuse flavor. Scalded milk also has a distinctly different flavor from plain old room temperature milk.
