Cantonese Crispy Pig (Ru Zhu / 乳猪)

Overview

Whole roast suckling pig is the pinnacle of Cantonese festive cooking — presented at wedding banquets, New Year feasts, and major celebrations. The skin is shatteringly crisp and bright red-amber while the flesh is tender. Preparation takes two days: seasoning, air-drying, and the special roasting technique using a hollow metal probe to inflate the skin away from the flesh creating the signature bubble-texture skin.

Flavour Context

The skin — shatteringly thin and crisp — is the entire point; the meat is secondary; the skin should be completely hollow from separation of fat layer

Key Principles

{"Suckling pig 3–6kg maximum — older pigs have insufficient fat under skin for proper crackling","Marinate cavity: five-spice, hoisin, soy, sugar, garlic, ginger, and fermented red bean curd for the red colour","Air-dry 24 hours in cool conditions after marinating — skin must be completely dry before roasting","Hollow inflation probe: insert under skin to separate skin from fat layer; this creates the distinctive crackled bubble texture"}

Pro Tips

{"Vinegar glaze brushed on skin during roasting adds additional browning and crispness","The cutting of the whole pig at the table is ceremonial — the suckling pig is the centrepiece first shown whole","At banquets: first 24 guests receive a square of the crisp skin — this is the prestige portion"}

Common Mistakes

{"Not sufficiently air-drying — skin steams instead of crackling","Using a pig that is too large — the crackling technique only works perfectly with young suckling pig","Not inflating skin from flesh — the skin fuses to meat without this step"}
