2Toast the Sichuan peppercorns in a dry pan for 1 minute, then grind to a powder.
3Heat the oil in a wok on medium high and fry the mushrooms and shiitake for 6 minutes until browned and dry.
4Lower the heat, add the doubanjiang and fry 1 minute. Add the black beans, garlic, ginger and chilli and fry 30 seconds.
5Add the stock, soy sauce and sugar, then slide in the tofu. Simmer 5 minutes, shaking the wok instead of stirring.
6Add the cornflour slurry in two or three parts, shaking between each, until the sauce turns glossy. Finish with chilli oil, spring onion and the ground peppercorn.
Serve it like this
Spoon into a shallow bowl so the red sauce pools around the tofu, then scatter peppercorn powder and spring onion over the top. Serve with plenty of rice.
