What You Need to Know
Gelatinization of corn starch occurs when temperatures reach 90–100 °C, swelling the granules and releasing amylose. Collagen in pork shoulder denatures into gelatin at 95–100 °C, creating a silky broth. Initial searing at 140–165 °C triggers Maillard browning, adding depth of flavor.
