Gently blanch the tofu cubes in lightly salted simmering water for 1 minute, then drain carefully.
Heat oil in a wok and brown the ground pork until crisp.
Add the doubanjiang, black beans, garlic, and ginger and stir-fry until the oil turns red and fragrant.
Pour in the stock and soy sauce and bring to a simmer.
Slide in the tofu and simmer gently for a few minutes, nudging rather than stirring to keep the cubes intact.
Stir the cornstarch with a little water and add it to thicken the sauce into a glossy coating.
Finish with chili oil and ground Sichuan peppercorns, scatter with spring onions, and serve with rice.
