scald: How to scald milk
To scald milk, simply heat it over medium heat, stirring, until bubbles begin to form around the edge of the pan. Always use a heavy bottomed pan to scald milk. Scalding used to be necessary to destroy harmful bacteria and enzymes in milk. That is no longer necessary, but scalding is still used in some recipes to bring out the flavor of certain ingredients like vanilla bean, citrus, and cinnamon, and to melt butter.
