Cantonese Suckling Pig (Kao Ru Zhu) Roast Tradition

Overview

Roasted suckling pig is the centrepiece of Cantonese ceremonies — weddings, business openings, festival banquets, grave-sweeping (Qingming). The whole pig, 3–5 kg, is marinated with five spice, fermented tofu, hoisin, and Shaoxing wine, then roasted in a dedicated oven over lychee wood for 2+ hours, basted constantly. The skin blisters into cracking 'glass skin' (jou pei) or 'milk skin' (nai you pei).

Flavour Context

Shatteringly crisp, blistered skin; rich, fatty pork; fragrant five-spice; sweet-savory from hoisin glaze

Key Principles

{"Two skin techniques: jou pei (crackled bubbled skin) vs nai you pei (smooth thin skin) — require different temperature management","Marinate cavity heavily, exterior lightly — skin must be dry for cracking","Stretch cavity with bamboo skewers — air circulation inside is critical","Begin high heat (250°C) for skin blistering, reduce (200°C) for interior cooking","Baste with vinegar-maltose glaze for colour — applied multiple times"}

Pro Tips

{"Professional chun pei shops do whole service — many caterers source from specialists rather than roasting in-house","The head and ears are the crispiest parts — prize pieces at any Cantonese table","First slice must reveal perfectly lacquered skin with even layer of fat beneath"}

Common Mistakes

{"Insufficient drying of skin before roasting — moisture prevents cracking","Single temperature throughout — two-stage heat essential for proper result","Insufficient marination of cavity — interior can be bland with overpowering exterior"}
