Xiba Tofu

Xiba Town sits along the Min River roughly 20 kilometers downstream from the Leshan Giant Buddha, where the Min and the Mangxi tributary converge and create a distinctive underground water system. The town's Liang Shui Jing well — cold, clear, low in dissolved minerals, perpetually replenished — has long been recognized as the reason the tofu made here differs from tofu made anywhere else; local tradition holds that 'without these two things, Xiba tofu loses its soul.' Written records document a thriving tofu trade in Xiba during the Ming Wanli era (approximately 1573–1620), giving the tradition at least 400 years of documented history; the Jiazhou Prefecture Gazetteer also preserves a folk legend crediting the discovery of tofu coagulation to the Song-dynasty Daoist hermit Chen Tuan, who allegedly stumbled upon it while tending his alchemist's stove at the Yuantong Temple in Xiba — though this is acknowledged local lore, not verifiable history. The craft became a family lineage through the Yang clan at Xiba's Qingyuan Shop, who began tofu production during the Qianlong and Jiaqing reigns of the Qing dynasty (late 18th to early 19th century); the seventh-generation master Yang Junhua expanded the original handful of recipes to over 300 and trained a generation of successors, including Zou Fangde, whose own restaurant became a landmark of the tradition. In 2009, the Wutongqiao Xiba Tofu-Making Craft was officially inscribed on Sichuan Province's second list of provincial Intangible Cultural Heritage.

Xiba tofu has a resilience ordinary tofu lacks: the exterior holds a quiet elasticity and the interior dissolves in the mouth with a clean, faint sweetness from the soybean that lingers after the bite is gone. Lantern Tofu multiplies the textural layers — after the first fry a thin crust forms; after the second fry over the egg batter, the shell has a springy crackle that breaks to reveal the tender tofu center knit with savory pork filling, fat and bean note intermingling. The doubanjiang red sauce adds chili heat and fermented-bean saltiness that dominate on first contact, pressing the bean sweetness toward the background — but the sweetness reasserts itself in the long, mellow finish.

The tofu's resilience starts with water chemistry. The Liang Shui Jing spring is a soft, weakly alkaline water low in dissolved minerals, so soy protein colloids form without interference from calcium or magnesium ions naturally present in harder water. Gypsum (calcium sulfate) is used as the coagulant rather than bittern (magnesium chloride): it sets more slowly and uniformly, building a finer, denser protein network that produces a tofu at once softer and more structurally sound — qualities that allow it to survive the mechanical stress of frying and stuffing without falling apart. For Lantern Tofu, two rounds of frying at graduated temperatures build the structural shell: the first fry at moderate heat drives off surface moisture and denatures the outer protein layer into a stable crust; the egg batter applied before the second fry at higher heat forms a second sealed layer within seconds of hitting the oil, locking the filling's juices inside and creating a double barrier that holds firm even under ladled sauce.
