What You Need to Know
Flash freezing in liquid nitrogen (-196 °C) reduces ice crystal size to <10 µm, preserving cellular structure and preventing drip loss. Subsequent sous‑vide cooking at 55–60 °C for 1–4 h denatures myosin and collagen uniformly, yielding a medium‑rare texture without overcooking.
