The signature flatbread of Lucheng in Shanxi's Upper Tang plateau: salted wheat dough layered with scallion and spiced salt, then swung in arcs over a rolling pin until paper-thin and round, before being griddled in donkey fat until golden and blistered. Traditionally rolled around cured donkey meat to serve, it won international gold at the 2003 Taiyuan Noodle Festival.
潞城甩饼 is the signature flatbread of Lucheng (潞城区), Changzhi City, deep in the Upper Tang plateau (上党) of south-east Shanxi. A local legend links it to Li Longji — the future Tang Emperor Xuanzong, who served historically as assistant prefect of Luzhou (景龙二年，708 AD) — who reputedly named the bread after watching a cook swing it round on a rolling pin. More reliable historical evidence lies in the Ming-dynasty 《潞州志》 and the Qing-dynasty 《潞安府志》, both of which record spring-festival flatbread traditions ('立春食春饼') in the Luzhou area, anchoring the pancake lineage to several centuries of documented practice. The cured donkey meat (腊驴肉) traditionally paired with the flatbread dates to the Yuan-Ming period, when Upper Tang traders processed ageing pack animals into cured meat; by the Republican era the combination was established street food. The flatbread won gold at the 2003 China Taiyuan International Noodle Festival and was designated a 'Shanxi Famous Snack' in 2004.
The flatbread is crisp at the outer char-blistered edges, softer and layered within; donkey fat lends a clean, faintly grassy richness distinctly lighter than pork lard. Rolled around the cured donkey meat — salty, smoky, chewy — and scallion strips, each bite alternates between crackle and tender yield.
Salt in the dough (about 1% by flour weight) strengthens the gluten network by reducing electrostatic repulsion between protein chains and promoting disulfide cross-links, giving the sheet enough tensile strength to sustain the centrifugal and gravitational forces of swinging without tearing. Folding with a film of donkey fat and scallion, then re-rolling, creates alternating fat-and-dough laminations — similar in principle to puff-pastry layering. During griddle cooking each fat-separated layer expands and steams independently, generating the characteristic flaky, blistered surface. Donkey fat has a relatively low melting point (approximately 30–35°C) and a higher proportion of unsaturated fatty acids than pork lard, vaporising quickly on the hot griddle to produce a lighter, crispier crust with a subtle, clean aroma.
Variations
The classical filling is cured donkey meat (腊驴肉); home versions substitute braised pork, spiced egg, or stir-fried leek-and-egg. In some areas the flatbread is made thinner still and served undipped as a single-pancake wrap (单饼), eaten with a garlic-vinegar dip. Lucheng's neighbouring counties of Huguan and Tunliu share similar griddle-flatbread traditions, but the combination of the swinging technique and donkey fat remains specific to Lucheng.

Ingredients
Serves 4How it's made
8 steps · 30 min
- 110 min
Dissolve 1 tsp salt in 150 ml warm water. Pour into 300 g wheat flour and mix; knead on the board for 10 minutes until the dough is smooth, satiny, and springs back when pressed.
- 220 min
Cover with a damp cloth and rest 20 minutes; the gluten will relax and the dough will become extensible without snapping back.
Watch outRest until the dough stretches without snapping back — swing it before it relaxes and the sheet tears mid-arc.
- 35 min
Divide into four equal portions. On a lightly oiled surface, roll each portion into a thin oval about 3–4 mm thick.
- 45 min
Brush the oval generously with melted donkey fat (or lard); scatter scallion rings and spiced salt evenly over the surface. Fold the oval in thirds as you would a business letter, then roll out again to about 3 mm thickness.
- 53 min
Drape the sheet over a rolling pin; lift the rolling pin and swing it in a smooth arc, rotating the dough a quarter-turn between each swing, until the sheet rounds out and thins evenly to about 2 mm across its full diameter.
Watch outRotate a quarter-turn between each swing and let the weight thin it evenly — swing too hard and it tears or thins in patches.
- 63 min
Heat a heavy iron griddle (鏊子) or cast-iron pan over medium-high heat until a drop of water vaporises instantly on contact. Brush the surface with a thin film of donkey fat; lay the flatbread on and cook until golden blisters form on the underside, about 2 minutes.
Watch outGriddle is ready when a water drop vaporizes on contact — lay it on too cool and you get pale, tough bread instead of blisters.
- 72 min
Flip with tongs; brush the second side with donkey fat; cook a further 2 minutes until both surfaces are golden with scattered char marks.
- 82 min
Slide onto a board; lay sliced cured donkey meat and scallion strips across the centre, roll tightly into a cylinder, and serve hot with Shanxi aged vinegar on the side.
