What You Need to Know
The Maillard reaction initiates above 140 °C, producing melanoidins and aromatic heterocycles that give the meat its smoky, caramelized flavor. Rendering of monounsaturated fat begins near 30 °C and completes by 60 °C, lubricating the surface and enhancing juiciness. Acidic chimichurri (pH ≈ 3.5) promotes surface protein denaturation, allowing flavor compounds to penetrate during grilling.
