World's best dishes: Sichuan peppercorn

It’s an obsession shared by many who love Chinese food: Sichuan peppercorns, or hua jiao.

The tiny, woody jewels that famously numb the lips are not peppercorns at all, but seed pods of the prickly ash tree.

The unique sensation they produce – likened by culinary scientist Harold McGee to ‘touching the terminals of a nine-volt battery to the tongue’ – comes from the world’s best-named molecule, hydroxy-alpha sanshool.

The shrub-like trees grow on hillsides in pockets of the vast countryside of China’s Sichuan province, with the best coming from Hanyuan County, three hours’ drive southwest of Chengdu, where the two distinct types of hua jiao are red and green – each with unique flavour profiles. They appear across Sichuan cuisine from malahuoguo (Sichuan hotpot) to huiguorou (twice-cooked pork belly); and from the tofu and minced pork dish, mapodoufu to the spicy noodle bowl, dandanmian.

But for this fan, one incarnation reigns supreme: guo kui, a street food snack. The finest example of these doughy flatbreads contains ground pork humming with hua jiao, chilli and salt, rolled into discs which are gently fried until golden and flaky. The crisp exterior gives way to heady spices and that unmistakeable tingling.

Chengdu’s definitive guo kui spot is a matter of considerable discussion – but for many, the original branch of Wang Ji Guo Kui, just inside the First Ring Road North, takes the prize. Sensational – literally – at any time, they’re best hot out of the pan on a cold Sichuan day.
