Savory Sauce Flatbread

The sauce-fragrant flatbread is claimed as a traditional specialty of the Tujia people (土家族) of the Enshi Tujia and Miao Autonomous Prefecture in western Hubei, where flatbreads flavored with bean paste have long appeared in local feast preparations. The dish entered national consciousness via street-food stalls in the early 2000s. Around 2009, vendors refined the spice formulation for broader palates and promoted the snack through early internet food communities; demand quickly outpaced supply at certain stalls. The snack spread rapidly under the nickname 'Chinese pizza' because the basic recipe—flour, water, oil, and two commercially available bean pastes—required minimal startup capital and equipment. Within a decade it had become one of the few pan-national street snacks without meaningful regional gatekeeping: sold identically in Harbin, Chengdu, Guangzhou, and Shanghai.

Shatter through crackling layers to a doughy-chewy interior—the bean paste is savory, sweet, and spiced all at once, the scallion adds a fresh sting, and sesame seeds exhale warmth. Oilier and richer than it looks.

The flatbread's flakiness comes from lamination: after kneading, dough is rolled thin, brushed with oil (sometimes mixed with flour to make a paste), folded, rolled again, and coiled into a disc. Each oil layer prevents gluten bonds from forming between adjacent dough sheets—so when the flatbread hits the hot pan, steam pressure puffs the laminae apart. The sauce layer (sweet wheat paste and Pixian doubanjiang) contributes two separate effects: at the pan contact surface it undergoes Maillard browning via its free amino acids and reducing sugars; deeper within the layers it acts as a flavor reservoir, releasing fermented-grain umami as the bread steams from within.
