What Is Sour and Spicy Potato (Suan La Tu Dou Si)?
💡 Ingredient Notes: Sour and Spicy Potato (酸辣土豆丝, suān là tǔ dòu sī) might be the most-cooked home dish in all of China — quick, cheap, universally loved. Potatoes are julienned into thin strips and stir-fried with black vinegar, dried chilies, and Sichuan peppercorns. The result should be crisp (not soft!), tangy, and gently spicy. It's the dish every Chinese college student learns to cook first. Deceptively simple but deeply satisfying when done right.
Ingredients You'll Need
The Dish
- 3 medium potatoes, julienned into thin matchsticks
- 5-6 dried red chilies
- 1 tsp Sichuan peppercorns
- 2 tbsp Chinese black vinegar
- 1 tbsp soy sauce
- 1 tsp sugar
- 3 tbsp cooking oil
- 2 cloves garlic, sliced
- 2 scallions, cut into lengths
📝 Instructions
Prep the potatoes
Julienne the potatoes into thin strips (about 3mm thick). Soak in cold water for 5 minutes to remove excess starch, then drain well. Dry potatoes stir-fry better.
Flavor the oil
Heat oil in a wok until smoking. Add dried chilies and Sichuan peppercorns. Fry for 15 seconds until fragrant — don't burn. Add garlic.
Stir-fry fast
Add the potato strips. Stir-fry over very high heat for 2-3 minutes. The potatoes should stay crisp — don't overcook. They should break when bent but still have a bite.
Season
Add vinegar (around the edge of the wok for aroma), soy sauce, and sugar. Toss for 30 seconds. Add scallions. Serve immediately.
💡 Pro Tips
- 💡Julienne the potatoes thin and even — this ensures quick, even cooking. A mandoline helps.
- 💡Soak the potatoes in cold water — removes starch so they stir-fry crisp instead of clumpy.
- 💡High heat and speed are essential — this dish cooks in 3 minutes. Don't walk away.
- 💡Keep the potatoes crunchy — they should NOT be soft. Think potato chips, not mashed.

❓ Frequently Asked Questions
Why are my potatoes mushy? Three causes: too thick (takes longer to cook), too much starch (didn't soak), or overcooked. Cut thinner, soak, and cook fast.
