Cantonese Crispy Pig (Ru Zhu / 乳猪)

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.

The Method

1
Combine five-spice, hoisin, soy sauce, sugar, garlic, ginger, and fermented red bean curd in a bowl and mix to a uniform paste. Apply the marinade exclusively to the interior cavity of the pig, coating all surfaces thoroughly. Leave the exterior skin untouched. The cavity should be fragrant and deeply coloured — red-amber from the bean curd.
2
Hang or prop the pig in a cool, well-ventilated space and air-dry for a full 24 hours. The skin must lose all surface moisture before roasting. At the end of the drying period, the exterior skin should feel taut and papery to the touch, with no trace of tackiness. A skin that is still soft or damp will steam in the oven rather than crackle.
3
This is the step on which the dish lives or dies. Using a hollow metal inflation probe, insert the tip under the skin at the neck or haunch and work it between the skin and the fat layer beneath. Blow air through the probe to separate skin from fat across the entire body. The skin will lift visibly away, standing proud of the flesh. Without this separation the skin fuses to the meat during roasting and the signature bubble-crackle texture cannot form.
4
Roast the pig, cavity side down, at high heat. During roasting, brush the skin repeatedly with rice vinegar. The vinegar accelerates Maillard browning and builds crispness. The skin is ready when it is shatteringly thin, bright red-amber in colour, and blistered into hollow bubbles across its surface — press lightly with a fingernail: it should crack like glass.
5
Present the whole pig at the table before cutting — this is the ceremonial centrepiece. Carve into portions. At a banquet, the first 24 guests receive a square of the crisp skin as the prestige portion.

Quality Hierarchy

01
Reserve — A suckling pig of 3–4 kg from a heritage or milk-fed breed, slaughtered to order, with an unbroken skin and an intact fat layer of even depth across the body.
02
Estate — A suckling pig of 4–6 kg from a reputable specialist butcher, confirmed milk-fed, skin intact; fermented red bean curd sourced from a Cantonese grocery for authentic colour and flavour.
03
Market — A small whole pig ordered from a Chinese or general wholesale butcher, within the 6 kg limit; commercial hoisin and soy sauce of reliable quality.
04
House — The same base pig but without breed provenance; jar hoisin and standard supermarket soy sauce; vinegar basting maintained throughout to compensate for a plainer skin.

Sensory Tests

◇Touch. After 24-hour air-dry, the exterior skin feels taut, papery, and completely dry — no tackiness or give anywhere across the surface.
◇Sight. After inflation, the skin stands visibly proud of the body, lifted away from the fat layer in an even dome.
◇Sight. When fully roasted, the skin is bright red-amber, blistered into hollow bubbles across the whole surface.
◇Touch. A fingernail pressed lightly into the roasted skin produces a clean crack — the skin is hollow, with no soft or fatty give beneath it.
◇Where it lives or dies. The inflation step — separating skin from fat with a hollow probe before roasting — is the one technique without which the dish cannot exist: no separation, no bubble-crackle skin.

What to Pour

A lightly aged oolong tea (traditional banquet accompaniment matching the richness of the skin) or, for a wine context, a delicate sparkling wine whose acidity and effervescence cut through the rendered fat without competing with the savoury cavity spices.
