What You Need to Know
At surface temperatures of 140–165 °C the Maillard reaction rapidly forms melanoidins, pyrazines and aldehydes that give the steak its characteristic smoky and nutty aroma. Internal temperatures above 60 °C cause excessive protein denaturation, leading to a dry, tough texture, while resting 5–10 minutes allows myosin fibers to relax and juices to redistribute for optimal tenderness.
