A flaky, multi-layered sesame flatbread from Mengcheng, Bozhou (Anhui): more than twenty gossamer-thin sheets of lard-laminated wheat dough, baked on the inner wall of a charcoal barrel kiln until the exterior shatters in translucent, oil-glistening shards. Anhui provincial intangible cultural heritage since 2006, and one of Mengcheng's 'Three Great Calling Cards' alongside Zhuangzi culture and its Yellow Cattle breed.
The earliest traceable history of the Mengcheng Crisp Sesame Cake points to the Qing dynasty Daoguang reign (1821–1850). An elderly man surnamed Song, living alone, operated a small stall on the west side of the gate of the Mengcheng Confucian Temple (文庙), selling barrel-kiln sesame cakes for his livelihood. He later took on Xue Yannian, a man from Shandong, as his apprentice. After Xue mastered the craft, he passed it on to his children and took in further disciples; the Xue family sesame cake grew in reputation and became a Mengcheng institution. The craft's third-generation bearer Xue Jucai (born 1958) has carried the tradition into the present. In 2006 the production technique was inscribed on Anhui Province's intangible cultural heritage register, cementing the cake's status alongside Zhuangzi culture as a defining symbol of Mengcheng.
Snap it in half and the layers fan open like the pages of a book — each one paper-thin, shimmering with rendered lard, shattering at the lightest pressure. The interior is softer but still distinctly layered, rich with the savoury sweetness of roasted sesame and melted pork fat. It finishes clean, without grease clinging to the mouth.
The Mengcheng cake's extreme flakiness is built on the physics of laminated dough: an elastic water dough (水面, gluten developed by hydration) encases an oil-fat pastry (油酥, lard worked into flour with no water), which is then rolled and folded repeatedly to multiply layers geometrically to 20 or more. The lard between each stratum forms a hydrophobic barrier that prevents gluten from cross-linking across layer boundaries — each sheet remains physically separate. Inside the barrel kiln (炉壁温度超过两百二十摄氏度), the small amounts of water trapped between the layers flash to steam, physically pushing the strata apart and creating the visible leaf-like separation. Simultaneously, the inter-layer lard melts and seeps outward, deep-frying each thin sheet from within at above its smoke point, rendering each one translucent and crisp rather than doughy.
Variations
The classic version is savoury, filled with chopped scallion and salt. Sweet variants substitute red-bean paste or jujube paste as filling. A halal adaptation replaces lard with vegetable shortening. Thicker, larger versions are sold as travel provisions; freshly baked thin ones from the kiln are the connoisseur's choice.

Ingredients
Serves 6How it's made
8 steps · 40 min
- 120 min
Make the water dough: combine flour, warm water and salt; knead for 8 minutes until smooth and elastic. Cover and rest 20 minutes.
- 210 min
Make the oil pastry: work rendered lard thoroughly into flour with your palms until the mixture forms a cohesive, shortening-like paste. No water is added.
Watch outWork the lard fully into the flour until the oil pastry holds together like soft shortening — dry crumbs here break the layers and the cake won't flake.
- 310 min
Roll the rested water dough into a large rectangle; place the oil pastry in the centre and fold the water-dough edges over to enclose it completely, as for rough puff pastry.
- 415 min
Roll the parcel into a long thin sheet; fold in thirds; rotate 90° and roll again. Repeat 4–5 times to multiply the layers to 20 or more.
Watch outRoll and letter-fold four or five times to stack twenty-plus layers, keeping the sheet even — an uneven roll bleeds the lard through and fuses the layers.
- 510 min
Divide the laminated dough into 12–16 portions. Roll each into a thin oval; sprinkle chopped scallion and salt across the surface; roll up tightly into a cylinder, then press flat with the palm into a round cake.
- 63 min
Coat one flat side of each cake generously with white sesame seeds, pressing firmly so seeds adhere.
- 72 min
Preheat the barrel charcoal kiln until the inner wall is too hot to hold your hand near. Using a long-handled spatula, press each sesame-coated cake firmly onto the hot inner wall of the kiln.
Watch outThe kiln wall must be too hot to hold your hand near before the cake goes on — a cool wall won't flash the trapped water to steam and the layers stay flat.
- 810 min
Bake 8–12 minutes until the cakes release naturally from the wall, showing a golden-brown crust and gossamer-thin, translucent layers. Remove with tongs and serve immediately.
