milk — scalded

Scalded milk is whole or low-fat milk that has been heated to approximately 180–185°F (82–85°C) for several minutes, a temperature below boiling. This thermal processing denatures whey proteins and alters the milk's physical and chemical properties without the prolonged effects of pasteurization or sterilization. Scalding is one of the oldest dairy preparation techniques, predating modern pasteurization, and was traditionally used to extend shelf life and improve safety before reliable refrigeration. The process creates a slight caramelized flavor, thickens the texture slightly, and reduces the activity of certain enzymes and microorganisms while leaving the milk still recognizable as fresh dairy.

Scalded milk has been employed across culinary traditions for centuries, particularly in baking, custards, and traditional fermented dairy preparations. The denatured whey proteins create a richer mouthfeel and improved emulsification properties compared to unheated milk.

Scalded milk is essential in traditional bread baking, particularly in yeast breads where it improves dough development, crust color, and loaf volume. It is also foundational in custard-based preparations, where the altered protein structure facilitates smoother incorporation into egg mixtures, reducing curdling risk. In fermented dairy preparations such as yogurt and kefir, scalding reduces competing microorganisms and helps establish the desired bacterial cultures more effectively. Traditional preparations for puddings, rice creams, and custard sauces often specify scalded milk. It is also employed in historical recipes for cream-based soups and old-fashioned baked goods where the subtle caramelization and body enhancement contribute to the final texture.
