Shanghai-Style Sauce Duck
酱鸭 · jiàng yā
My uncle in Jing'an cooked this for Mid-Autumn Festival — he’d marinate the duck overnight in his courtyard, hanging it from a bamboo pole so sparrows couldn’t steal the soy scent. He swore the city’s humid autumn air made the skin cling tighter to the meat.

whole duck (2.2–2.5 kg), giblets removed: Ask butcher to remove excess fat around cavity; pat skin very dry before marinating.
dark soy sauce: Essential for mahogany color and umami backbone.
rock sugar: Crush with mortar or rolling pin — granulated sugar burns too easily.
Shaoxing wine: Do not substitute rice vinegar or apple cider vinegar — acidity disrupts gelatinization.
star anise: Use whole, not ground — infuses slowly without bitterness.
ginger, 3 thick slices: Smash lightly with knife spine to release oils.

Tips
- · Use a duck with tight, unblemished skin — avoid frozen-thawed if possible.
- · Slice against the grain for maximum tenderness and clean cuts.
- · Leftover sauce freezes well for braising tofu or eggs.

Common questions
Can I skip Shaoxing wine? What's the substitute?
Dry sherry is the closest 1:1 swap (fidelity ~80%). No sherry? Use a splash of white wine plus a little water, or just skip it and add a tiny extra pinch of sugar — the wine's job is depth and removing meat's gamey notes, and a good marinade covers most of it.

Is there a vegan substitute for oyster sauce?
Yes — 'mushroom oyster sauce' (often labeled vegetarian/vegan) is sold in most Asian grocers and increasingly in mainstream supermarkets. It behaves 1:1 and adds the same glossy umami. Watch labels if you're also gluten-free; most brands are GF, some aren't.

What's the difference between light and dark soy sauce?
Light soy (生抽) is the everyday salty seasoning — thin and salty, used in most recipes. Dark soy (老抽) is thicker, darker, slightly sweet, and used mostly for color (braises, fried rice). If you only buy one, get light soy. For dark soy's color: 1 tbsp light soy + a pinch of sugar + a few drops of molasses.
