What You Need to Know
Intestinal collagen denatures at 60-70°C while myoglobin oxidizes, with simultaneous fat rendering creating a lubricating lipid matrix. Surface temperatures exceeding 150°C induce Maillard reactions and pyrolysis of exterior proteins.
Achieves perfect textural contrast between crispy charred exterior and gelatinous interior, while marinade caramelization adds complex umami-sweet notes.
