Raw peanuts slow-fried in cold oil until deeply golden, then hit while still hot with a dressing of Shanxi aged black vinegar, sugar, and soy sauce. The first spoonful goes down with a crack; the vinegar clears the palate for the next.
The dish is native to Shanxi, where aged black vinegar—produced in the Qingxu and Taiyuan regions using a summer-sun-drying and winter-freeze-concentration technique first documented in the Ming Dynasty—is the kitchen's default acid. Peanuts arrived in China from South America in the 16th century and were quickly deep-fried and salted as a snack in northern kitchens. The pairing of fried peanuts with aged vinegar appears as a named dish in Shanxi cooking literature by the Republican era, and has since spread nationally as a standard cold-dish opening.
A nugget that snaps between the teeth with satisfying force; the red skin crackles, the kernel exhales its roasted nuttiness, and then the vinegar—sharp and deep and slightly sweet—cuts right through.
Starting peanuts in cold oil and raising heat gradually allows the interior to cook through before the surface browns, producing a crunch that extends to the core rather than just a brittle shell. At 150–170°C, Maillard reactions and pyrazine formation generate the characteristic roasted aroma. The critical technique: the vinegar-sugar-soy dressing is poured over hot peanuts. The heat flash-evaporates some acetic acid, muting raw sharpness, while the sugar and salt quickly penetrate the warm, slightly porous surface. Peanuts absorb moisture and soften within 20–30 minutes; the dish must be eaten immediately.
Variations
A Sichuan variant adds chilli oil and Sichuan pepper powder for a mala version. Cantonese restaurant versions use milder Zhenjiang black vinegar and add sliced spring onions for colour. Some northern households add finely diced red onion and fresh coriander to brighten the dish. A sweeter Fujian variant uses local red vinegar and candied ginger, making it more of a snack than a salad.

How it's made
6 steps · 25 min active + 5 min waiting
- 13 min
Sort peanuts and discard any shrivelled ones; pat completely dry with a kitchen towel.
- 23 min
Finely dice red onion; roughly chop fresh coriander. Set aside.
- 32 min
In a small bowl, stir together aged black vinegar, sugar, light soy sauce, and salt until sugar dissolves.
- 412 min
Place peanuts in a cold wok; add enough oil to just cover. Turn heat to medium-low and fry, stirring constantly, until skins turn deep red and a test peanut is golden-crisp inside, about 10–12 minutes.
Watch outStart the peanuts in cold oil over low heat and stir constantly — this cooks them crisp to the core; drop them into hot oil and the skins scorch before the inside crunches.
- 55 min
Drain peanuts on a rack or paper towel; spread out to cool for 5 minutes.
- 63 min
Pour vinegar dressing over warm peanuts; add red onion and coriander, toss to coat, and serve within 15 minutes.
Watch outPour the vinegar dressing over the peanuts while still warm and eat within 15 minutes — they drink up moisture and go soft fast.
