If using a protein that needs cooking, start by frying it in hot oil until almost done

Stir fry the chillies, garlic, Sichuan pepper, scallion whites and douchi until the garlic starts to brown and the chillies are toasted

Add the leafy greens, then the rice cakes and stir fry for a minute

Add the fried tofu if using, then the Shaoxing wine and cover for 1 minute

Add the douban jiang, sugar and soy sauce and stir for a minute until the rice cakes are soft but still chewy. If it gets too dry add a splash of water

Add the scallion greens and coriander and serve
