Culinary Science: The Mayo Trick & Thermal Management
-
Why Mayonnaise Yields a Crisper Crust: Mayonnaise is an emulsion of oil and egg protein. Unlike plain butter (which contains ~16–18% water that steams the bread), mayonnaise coats the sourdough in pure oil and protein. The egg proteins accelerate the Maillard reaction, creating an even, deep-golden crust without burning or going soggy.
-
Low-Heat Thermal Melt: Ground beef holds significant thermal mass. Cooking over low to medium-low heat allows heat to gently penetrate the dense filling and melt both layers of cheese fully before the bread exterior burns.
