Steamed Hairy Crab
清蒸大闸蟹 · qīng zhēng dà zhá xiè
My aunt in Suzhou still steams crabs in a bamboo basket over boiling water every Mid-Autumn Festival — she says her mother taught her to tie each crab belly-up with cotton string so the roe stays sealed inside. We eat them bare-handed, cracking shells with chopsticks and sipping warm chrysanthemum tea.

Instructions
1Rinse crabs under cold running water; use a soft brush to gently scrub shells and legs. Pat dry with paper towels.
刷净、擦干
🔍 Look for 2 分钟 · 2 minutesVisual: 蟹体洁净发亮,无泥沙附着。Crabs are clean, shiny, and free of visible debris.
You know it's right when: 拇指轻搓蟹壳无砂砾感。No grit remains when rubbing shell with thumb.
2Grate 20 g ginger (reserve remaining 10 g). Place crabs belly-up on a heatproof plate. Tuck 1 tsp grated ginger and ½ tsp Shaoxing wine into the cavity of each crab.
腹朝上,姜酒入脐
🔍 Look for 3 分钟 · 3 minutesVisual: 姜末均匀填入蟹腹腔内。Ginger is evenly distributed in the crab's abdominal cavity.
You know it's right when: 蟹腿自然收拢,未散开。Crab legs remain tightly tucked, not splayed.
3Bring a wok or large pot with 5 cm water to a vigorous boil over high heat. Place crabs on a bamboo steamer lined with cabbage leaves (to prevent sticking), then set steamer over wok.
水沸再上笼
🔍 Look for High heat 1–2 分钟 · 1–2 minutesVisual: 水面剧烈沸腾,白雾状蒸汽升腾。Water bubbles vigorously; steam rises thick and white.
You know it's right when: 锅盖边缘持续稳定冒汽。Steam escapes steadily from lid edges.
4Cover and steam over high heat for 15 minutes for 150 g crabs (add 2 minutes per additional 25 g). Do not lift lid during steaming.
全程勿开盖
🔍 Look for High heat 15 分钟 · 15 minutesVisual: 蟹壳转为鲜亮橙红,蟹黄呈不透明金黄色。Crab shells turn bright orange-red, and roe becomes opaque golden-yellow.
You know it's right when: 厨房弥漫浓郁清甜蟹香。A rich, sweet-crustacean aroma fills the kitchen.
5Meanwhile, make ginger-vinegar sauce: finely mince remaining 10 g ginger, mix with black vinegar and a pinch of white pepper. Serve alongside hot crabs.
现拌姜醋汁
🔍 Look for 2 分钟 · 2 minutesVisual: 酱汁呈浅琥珀色,浮有细姜粒。Sauce is pale amber with visible ginger flecks.
You know it's right when: 姜味清新辛香,未经加热。Ginger aroma is sharp and clean, not cooked.
Tips
- · Always steam crabs belly-up to retain roe and juices.
- · Use only female crabs in autumn (Sept–Nov) for maximum roe.
- · Never reheat steamed crab — serve immediately while hot.

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.

Why do you cook the aromatics (garlic/ginger) first on low heat?
Aromatics contain oils and sugars that turn bitter if scorched. Gentle heat (low-medium) lets garlic and ginger release their fragrance without browning too fast. If the pan is too hot, garlic goes bitter within seconds — that's why we always add aromatics first, before the main ingredients.
