The Cantonese roast meats (siu mei) tradition displays its products hanging in the window — a visual argument for quality. A properly roasted goose in a siu mei shop in Hong Kong or Chinatown hangs upright, neck extended, in a deep mahogany color that suggests lacquer rather than skin. The color comes from the maltose glaze applied before roasting: maltose (malt sugar) caramelizes at lower temperatures than sucrose and produces a darker, more even color and a distinctive candy-gloss surface.
The air-pumping step is the technique that separates a properly made roast goose from a home-roasted bird: after cleaning, a straw or pump is inserted at the neck cavity and air is blown between the skin and the flesh, inflating the skin away from the body. The separation allows the fat beneath the skin to render freely during roasting (fat can drain out rather than being trapped between skin and flesh) and allows air to circulate between skin and flesh in the oven — both effects produce crispier skin. The skin must then be air-dried thoroughly (overnight in a cool space) before roasting; any surface moisture turns to steam in the oven and prevents crisping.
The cavity stuffing is the flavor engine: a mixture of soy sauce, Shaoxing wine, five-spice, sugar, and aromatics is poured into the cavity, the neck and tail are sealed (skewered closed) so the stuffing doesn't escape, and during roasting the liquid steams the interior of the bird from the inside while the outside crisps.
The Process Overview
Day 1 — Prep:
- Clean and dry the goose thoroughly; remove excess fat deposits at the neck and cavity
- Mix and pour the cavity stuffing inside; seal both openings with a skewer
- Blanch the outside briefly in boiling water (causes skin to tighten)
- Air-pump the skin (using a straw or pump at the neck opening) to separate skin from flesh
- Coat the outside with the maltose-vinegar glaze
- Hang the goose in a cool, well-ventilated place (or in front of a fan) overnight to air-dry
Day 2 — Roast:
- Roast in a very hot oven (230–250°C) hanging or on a rack for 45–60 minutes, rotating once
- The skin should reach mahogany; the internal temperature should reach 74°C
The Cavity Stuffing
- 3 tablespoons soy sauce
- 2 tablespoons Shaoxing wine
- 1 tablespoon oyster sauce
- 1 tablespoon hoisin sauce
- 2 teaspoons five-spice powder
- 1 tablespoon sugar
- 4 garlic cloves, smashed
- 4 slices fresh ginger
- 2 scallion stalks
Mix all ingredients; pour into cavity; seal openings.
The Maltose Glaze
- 3 tablespoons maltose (or honey as substitute)
- 2 tablespoons Chinese rice vinegar
- 1 teaspoon red fermented bean curd juice (optional, for color)
- 80ml boiling water to dissolve
Mix; brush generously over the outside of the goose after air-pumping.
The Complete Recipe
Serves: 4–6 | Time: 2 days (including overnight drying)
Ingredients
- 1 whole goose (approximately 3–4kg), cleaned
- Cavity stuffing (above)
- Maltose glaze (above)
Serving
- Plum sauce or sweet soy dipping sauce
- Steamed white rice or egg noodles
Method
Day 1: 1. Clean goose; pat dry. Remove excess fat at cavity opening. Mix cavity stuffing ingredients; pour into the cavity. Seal neck and tail openings with metal skewers.
2. Blanch: Lower goose into a large pot of boiling water for 30 seconds; remove. (Tightens skin.)
3. Air-pump: Insert a straw or pump at the neck area; blow air between skin and flesh, working around the bird to separate skin from flesh all over. The skin will puff slightly.
4. Glaze: Brush the maltose glaze evenly over all surfaces. Hang or place on a rack; allow to air-dry uncovered overnight in a cool, well-ventilated space (or refrigerator with a fan, or in front of a fan at room temperature).
Day 2: 5. Preheat oven to 230°C. Hang the goose upright (hook through neck, tail down) in the oven or place breast-side up on a wire rack over a drip tray. Roast 20 minutes; rotate; roast 20–30 minutes more. If skin is browning too fast, loosely tent with foil (though this sacrifices crispiness).
6. The goose is done when the skin is deep mahogany and the thigh juices run clear. Internal temperature at thigh: 74°C.
7. Rest 10 minutes before chopping. Drain the cavity stuffing juices into a small bowl — they are intensely flavored and can be served alongside as a dipping sauce or drizzled over the meat.
Chop into pieces (Chinese-style through the bone) with a cleaver; serve with plum sauce and white rice.
