Suan Cai Yu (Hot & Sour Pickled Mustard Greens Fish Stew)
酸菜鱼 · suān cài yú
My aunt in Chongqing’s Yuzhong District taught me this when I was 12 — she’d simmer the broth while I shredded the suan cai, saying, 'The sourness must bloom before the heat arrives.' Her clay pot still sits on my stove.

fresh tilapia fillets: Look for skinless, boneless fillets; cod or basa may substitute but tilapia holds texture best.
Sichuan-style pickled mustard greens (suan cai): Must be fermented, not vinegar-brined — check label for 'lactic acid fermented' or 'no added vinegar'.
dried red chilies: Use mild-to-medium heat varieties like facing heaven or er jing tiao; remove seeds for less heat.
Sichuan peppercorn: Toasted whole Sichuan peppercorns preferred — avoid pre-ground (loses aroma fast).
ginger: Young ginger preferred for tenderness and milder bite.

Instructions
1Rinse suan cai under cold water 3 times to remove excess salt; squeeze dry and roughly chop. Set aside.
去盐控水
🔍 Look for Low heat 2 分钟 · 2 minutesVisual: 酸菜呈浅橄榄绿,攥紧后无卤水滴落。Suan cai turns pale olive-green, no brine dripping when squeezed.
You know it's right when: 表面无可见盐粒结晶。No visible salt crystals remain on surface.
2Heat 2 tbsp neutral oil in a heavy-bottomed pot over medium heat. Add dried chilies and Sichuan peppercorns; toast 45 seconds until fragrant and slightly darkened.
焙香料
🔍 Look for Medium heat 45 秒 · 45 secondsVisual: 辣椒微微鼓起,油面浮现金色细点。Chilies puff slightly; oil shimmers with tiny golden flecks.
You know it's right when: 厨房弥漫温暖麻香。Aromatic, warm numbing scent fills the kitchen.
3Add ginger and stir 1 minute until edges turn translucent. Stir in suan cai; cook 3 minutes until aroma deepens and liquid reduces slightly.
激香姜与酸菜
🔍 Look for Medium heat 4 分钟 · 4 minutesVisual: 姜丝变软,酸菜颜色微深,腾起微酸热气。Ginger softens; suan cai darkens slightly and releases tangy steam.
You know it's right when: 酸香发酵味明显增强,不刺鼻不呛喉。Tangy, fermented fragrance intensifies — not sharp or sour-smelling.
4Pour in 1.5 L hot water (or fish stock if available). Bring to gentle boil, then reduce heat to low. Simmer uncovered 15 minutes.
熬出醇厚汤底
🔍 Look for Low heat 15 分钟 · 15 minutesVisual: 汤面轻漾涟漪,边缘聚薄层白沫。Surface ripples softly; thin white foam gathers at edges.
You know it's right when: 酸香清正,无生酵异味。Clear, clean sour aroma — no raw fermentation smell remains.
5Season with 1 tsp salt and 1 tsp white pepper. Gently slide fish slices into simmering broth one by one. Poach 4–5 minutes until opaque and just firm — do not stir vigorously.
轻柔浸煮鱼片
🔍 Look for Low heat 4–5 分钟 · 4–5 minutesVisual: 鱼片全白微粉,边缘微卷,中心略显柔润。Fish turns fully opaque white with faint pink center; edges curl slightly.
You know it's right when: 按压微弹不硬,绝不可发柴。Firm but yielding to gentle pressure — never rubbery.
Tips
- · For deeper umami, simmer fish bones (head + frame) in water 20 min before step 4 — strain and use as broth.
- · Serve immediately: residual heat continues cooking fish. Overcooking makes it mushy.
- · Top with fresh scallion greens and a drizzle of chili oil just before serving.

Common questions
I can't find Sichuan peppercorns. What do I use?
Honestly, there is no true substitute — the numbing (má) sensation is unique. Best local approximation: 1/2 tsp black pepper + a little citrus zest for warmth and brightness. If you cook Sichuan food regularly, buy them online; they keep for months in an airtight jar.

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.

I only have 30 minutes. Which recipes should I pick?
Look for the 'Quick' filter (≤30 min) — tomato & egg, egg fried rice, scallion pancakes, beef & broccoli, and mapo tofu (if you have doubanjiang) all fit. Prep tip: mise-en-place everything first; the actual cooking is usually under 10 minutes.
