The Searing Truth: Does Browning Meat Really Seal in Juices?

The myth that a quick sear creates an impenetrable crust preventing moisture from escaping was popularized in the 19th century by chemist Justus von Liebig. However, culinary science, notably advanced by Harold McGee, has repeatedly demonstrated that searing's primary benefit is the development of rich, complex flavors and a desirable browned crust through the Maillard reaction. This chemical process generates hundreds of new flavor compounds. While searing vastly improves taste and texture, for maximum juiciness, precise temperature control throughout cooking and allowing the meat to rest are far more critical than the initial high-heat sear.
