Kou Shui Chicken (口水鸡)
口水鸡 · kǒu shuǐ jī
Kou Shui Chicken (口水鸡) is named for the effect it has on diners — the sight and aroma are so irresistible that saliva flows involuntarily ('kou shui' literally means 'mouth water'). Originating from Chengdu street food stalls in the 1930s, it is now a staple of Sichuan cold dish menus. The technique is elegant: a gentle poach preserves the chicken's juiciness, an ice bath locks in firm texture, and the sauce — a balance of chili oil heat, Sichuan peppercorn numbness, soy saltiness, and sesame aroma — is where the magic lives. Serve at a restaurant, and it arrives glistening in its own red oil, studded with crushed peanuts and fresh scallion.

Instructions
1Prepare the poaching liquid. Fill a pot large enough to hold the chicken in a single layer with about 1.5 L water. Add ginger slices, knotted scallions, Shaoxing wine, and 1 tbsp salt. Bring to a boil over high heat, then reduce to a gentle simmer.
🔍 Look for Medium heat 约 3 分钟至微沸 · about 3 minutes to reach simmerVisual: 汤面间歇冒小泡,液体带着姜葱的香气Small bubbles break the surface intermittently; the liquid is lightly aromatic with ginger and scallion
You know it's right when: 汤面微滚,非大沸Surface is gently agitated, not a rolling boil
2Lower the chicken legs into the simmering liquid. Cover and poach for 12–15 minutes (for bone-in thighs) or 10–12 minutes (for boneless). Do not boil aggressively — a vigorous boil will tighten the meat and make it dry.
🔍 Look for Medium-low 12–15 分钟 · 12–15 minutesVisual: 鸡皮呈不透明的白金色;最厚处用签子穿刺,流出清澈汁水Chicken skin turns opaque white-gold; juices run clear when the thickest part is pierced with a skewer
You know it's right when: 内部温度达 74°C;汁水清澈不泛粉Internal temperature reaches 74°C / 165°F; juices run clear, not pink
3Immediately transfer the cooked chicken to a bowl of ice water. Submerge completely and leave for at least 10 minutes — this shocks the skin into contracting, creating the signature gelatinous, bouncy texture. Leave until completely cool.
🔍 Look for 冰水中 10–15 分钟 · 10–15 minutes in ice waterVisual: 鸡皮饱满光滑,略带胶质光泽——热冲击后的收缩效果Chicken skin appears plump, smooth, and slightly gelatinous — a visible shrink-wrap effect from the thermal shock
You know it's right when: 鸡肉中心已冷,鸡皮明显收紧Chicken is cold to the core; skin has tightened noticeably
4Make the sauce. In a medium bowl, whisk together chili oil (with sediment), toasted ground Sichuan peppercorn, sesame oil, light soy sauce, Chinkiang vinegar, minced garlic, and sugar until the sugar dissolves. The sauce should be a deep red-orange, glossy, with a visible layer of chili oil on top.
🔍 Look forVisual: 深红橙色液体,油亮光泽,悬浮辣椒碎和蒜末Deep red-orange liquid with a glossy sheen; tiny chili flakes and garlic bits suspended throughout
You know it's right when: 糖完全溶解,质地均匀无颗粒Sugar is fully dissolved; the mixture is homogeneous with no grainy patches
5Remove chicken from ice water and pat dry with paper towels. Cut into bite-sized pieces (about 2-inch chunks) on a cutting board — the bone can stay in for easier handling. Arrange on a serving platter and generously ladle the chili-sesame sauce over the top, ensuring every piece is coated. Sprinkle with crushed peanuts and sliced scallions. Serve immediately or chill for up to 2 hours for deeper flavor.
🔍 Look forVisual: 盘中鸡块红油泛光,花生和葱花点缀出红绿对比Platter is glistening with red oil; peanuts and green scallion provide color contrast against the deep red chicken
You know it's right when: 每块鸡都裹上红油,盘底有少量酱汁汇集Each piece has a visible coating of chili oil; the sauce pools slightly at the base of the platter
Tips
- · The ice bath is non-negotiable. Skipping it means the skin stays soft and the texture is disappointing. Ten minutes in ice water makes the difference between 'meh' and 'wow'.
- · Use good-quality chili oil with visible sediment (辣椒碎). The sediment is where the flavor lives — oil alone is just heat without complexity.
- · Toasted Sichuan peppercorn (花椒) is essential for the 'má' (numbing) sensation. Dry-toast whole peppercorns in a pan until fragrant (1 minute), then grind coarsely. Pre-ground loses potency within weeks.
- · Kou Shui Chicken tastes even better the next day — the sauce has penetrated deeper into the meat. Make it ahead for maximum impact.

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.

It's too spicy. How do I tone it down?
Add a dairy element (a swirl of yogurt, milk, or a spoon of peanut butter) — dairy fat binds the capsaicin. Sugar or honey also helps balance heat. For next time: remove chili seeds (they hold most heat) or halve the dried chilies and add chili oil at the table instead.

Can I reduce the salt/soy in this recipe?
Yes — soy sauce is the main sodium source. Use light soy at 2/3 amount and finish with salt only to taste. Rinse canned/doubanjiang components if possible. Note: reducing soy also reduces color; a drop of dark soy or a pinch of sugar can restore depth without salt.

Ingredient swaps
Can't find an Asian-market staple? Use these.
Swap: Shaoxing wine
→ dry sherry or mirin (less sweet)
Ratio: 1:1 · Both add the same warm fermented depth.
Swap: toasted sesame oil
→ toasted sesame oil (same thing!)
Ratio: 1:1 · Check the label: use toasted (dark), not raw.
Swap: light soy sauce
→ regular soy sauce
Ratio: 1:1 · Slightly saltier — dial salt back by a pinch.
Don't make these mistakes
The traps every home cook hits — and how to avoid them.
✗ Crowding the pan — ingredients steam instead of sear.
✓ Fix: Cook in batches; give each piece room to brown.
✗ Adding sauce too early — the wok cools and flavors dull.
✓ Fix: Push food up the wok wall, add sauce to the hot center, toss fast.
