Thin-sliced pork liver given two brief flashes of high heat, then tossed in a sweet-tart pan sauce of rice vinegar, soy sauce, and sugar, finished with a thread of sesame oil. The result is liver just past pink — silky at the centre, faintly caramelised at the edges, without a trace of iron or must. In Fuzhou, a plate of this dish tells you whether a restaurant is serious.
The dish's name is a Fuzhou-dialect pun: the word for 'two' (两) sounds in Fuzhou speech very close to 'south' (南), so 两煎肝 — 'twice-fried liver,' naming the two stages of heat — shifted over time into 南煎肝. A rival etymology credits the literary translator Lin Qingnan (琴南), who is said to have introduced this Fuzhou specialty to Beijing friends in the early twentieth century, giving rise to the written form 南荐肝. The dish spread from Fuzhou to Yongan county in the 1930s and was formally listed in Fuzhou's first batch of Protected Min Cuisine in 2021.
Silky liver slides across the tongue — barely cooked at the centre, faintly sweet-sour, with sesame oil blooming quietly at the finish. No trace of iron or offal.
Pork liver is dense with iron-carrying myoglobin proteins that turn grainy and grey if heated past 70°C. The vinegar-water soak denatures surface blood proteins in the acidic environment, making them coagulate and float free, without raising internal temperature. The short oil-bath — 10 to 15 seconds at roughly 180°C — sets the outer layer with Maillard browning while leaving the interior at around 60°C, enough to eliminate pathogens while keeping proteins tender. The finishing acid-sugar sauce binds iron compounds to suppress residual metallic aroma, and the toasted aromatic esters in sesame oil provide a volatile top note that signals freshness before the first bite.
Variations
Some Fuzhou cooks add half-rings of white onion for aromatic contrast. In Yongan, where the dish arrived in the 1930s, the sauce runs slightly sweeter and sometimes includes a dash of local distilled liquor.

How it's made
7 steps · 10 min
- 15 min
Slice the pork liver — preferably the tapered tip — to about 5 mm using a very sharp knife; angled cuts increase the surface area exposed to heat.
- 210 min
Soak the slices in cold water with 1 tablespoon of white vinegar for 10 minutes; the acid coagulates blood proteins into dark flecks that rinse away. Drain and pat thoroughly dry.
Watch outSoak the sliced liver in vinegar-water ten minutes — the acid coagulates the blood into dark flecks that rinse away, then dry it well.
- 35 min
Marinate with light soy sauce, white pepper, and a pinch of sugar for 5 minutes.
- 43 min
Mix the pan sauce: stir aged rice vinegar, sugar, dark soy sauce, rice wine, and cornstarch together in a small bowl until the starch dissolves.
- 52 min
Heat a wok over the highest flame until smoking. Add oil and flash-fry the liver in a single layer for 10–12 seconds, turning once; remove the instant edges just begin to colour.
Watch outFlash-fry the liver ten to twelve seconds and pull it the instant the edges color — past 70 degrees inside it turns grey and grainy.
- 62 min
In the same wok, add minced garlic, sizzle 5 seconds, pour in the pan sauce and stir until it thickens to a glaze.
Watch outSizzle the garlic just five seconds before the sauce goes in — let it brown and the whole glaze turns bitter.
- 72 min
Return the liver, toss vigorously for 3 seconds to coat in the sauce, drizzle with sesame oil, and plate immediately.
