酸辣土豆丝（快手川菜风格）—— 15 分钟家常素炒 · suān là tú dòu sī

家庭快手版 · Home version: Home-style fast stir-fry. Potatoes are rinsed thoroughly to remove starch for extra crunch; vinegar is added at the end to preserve its bright acidity.

This is the most ordered vegetable dish in Sichuan home kitchens and cheap-eat restaurants alike. Thin julienne potato strips are flash-fried with dried chilies and Sichuan peppercorns, then dressed with Chinkiang vinegar for that signature sour-spicy kick. It is the dish that teaches beginners the wok's two golden rules: high heat and speed.

Ingredients

dried red chilies, whole干红辣椒段🏮 asian8-10 pieces
Sichuan peppercorns花椒🏮 asian1 tsp

yellow-flesh potato: Yellow or waxy potatoes hold shape better than floury baking potatoes. Peel and cut into 5-cm matchsticks (2 mm thick).

dried red chilies, whole: Use whole dried chilies, slit open and shake out seeds for milder heat; keep seeds for extra kick.

Sichuan peppercorns: Red Sichuan peppercorns give more aroma; green gives more numbing heat. Either works.

Chinkiang (black) vinegar: Added at the end for bright acidity. Do not substitute with white vinegar — the malty depth is essential.

light soy sauce: A splash for savory depth; use sparingly to keep the dish pale and focused on sour-spicy.

neutral cooking oil: Peanut or canola oil preferred for high-heat stir-frying.

scallion, chopped: Garnish added at the very end for color and fresh onion bite.

Instructions

1Julienne potatoes and rinse. Cut peeled potatoes into 5-cm matchsticks (2 mm thick). Soak in cold water for 2 minutes, then drain and pat completely dry with a clean towel — excess moisture kills the wok hei.

2Heat wok until smoking. Add neutral oil and swirl to coat. Add dried chilies and Sichuan peppercorns; stir-fry 10 seconds until fragrant but not burned — burnt peppercorns turn bitter.
🔍 Look for High heat 约 10 秒

You know it's right when: 闻到辛辣香气立即下土豆，不可等辣椒变黑
3Add drained potatoes. Toss immediately on high heat for 60-90 seconds. The potatoes should sizzle loudly and begin to char slightly at the edges.

Do not cover the wok — trapped steam makes potatoes soggy.

5Finish with Chinkiang vinegar. Pour along the hot wok wall (not over the potatoes) so it sizzles and caramelizes slightly. Toss once more for 10 seconds, add scallions, and plate immediately.

Adding vinegar at the end preserves its bright acidity — adding it early cooks off the tang.

Tips

· Rinsing potato starch is the single most important step — it guarantees crunch, not mush.
· High heat is non-negotiable. If your wok smokes, you are ready.
· Vinegar goes in last — this is what makes the dish sour-spicy rather than just spicy.
· Serve immediately. Potato shreds lose crispness within 3 minutes of sitting.
