Char siu is a Cantonese-style Chinese BBQ pork traditionally roasted on skewers in a wood-fired oven, resulting in a distinctive mahogany-red exterior with sweet and savory caramelized edges. The name literally means "fork roasted," referring to the traditional cooking method. Sous vide revolutionizes this beloved dish by ensuring the pork becomes incredibly tender and juicy while absorbing the complex marinade of hoisin, soy sauce, honey, five-spice, and red fermented bean curd. The water bath's precise temperature control cooks the pork evenly throughout without the risk of drying out that plagues traditional high-heat roasting. After the bath, a quick high-heat finish with frequent basting creates the signature sticky, caramelized glaze and slightly charred edges that define great char siu. Whether sliced over rice, chopped for fried rice, or served in steamed buns, sous vide char siu delivers consistent restaurant-quality results that rival the best Chinatown roast shops.
