Chen Mapo Tofu (陈麻婆豆腐, Chén Mápó Dòufu)

Mapo tofu was invented in Chengdu in the 1860s at a small restaurant run by a woman with a pockmarked face — má pó, literally "pockmarked grandmother." Her recipe was silken tofu simmered in fermented broad-bean chili paste (豆瓣酱, dòubànjiàng) with minced beef, garlic sprouts, and a heavy shower of ground Sichuan peppercorn. The restaurant that carries her name still operates on Xiyulong Street, a few hundred metres from the original site.

The dish arrives in a shallow bowl, dark red and glossy, still bubbling. The tofu is soft enough to collapse if you're careless with the spoon. The first mouthful is savoury and deep rather than aggressively hot; the numbness builds over about thirty seconds until your lips genuinely tingle. Compared to versions served abroad — thickened, sweetened, made with firm tofu — it's a different dish entirely.

Honesty about the venue: this is a large, brightly lit, multi-floor operation with laminated picture menus and a steady flow of tour groups and Chinese domestic tourists. The service is brisk and functional. Prices are 20–30% above a neighbourhood restaurant, though ¥28–38 ($3.90–5.30) for the signature plate is hardly extravagant.

Is it the best mapo tofu in Chengdu? Probably not — plenty of unremarkable canteens make a version just as good for ¥18 ($2.50). But it is the origin story, the reference point, and the plate against which you'll judge every mapo tofu afterwards. Go once, order rice, and don't drink cold water with it.
