Bring a pan of salted water to a gentle simmer. Add the tofu cubes and blanch for 2 minutes. Drain carefully and reserve. The cubes should hold their shape and be uniformly heated through — the surface will appear just set.

Heat 3 tablespoons of oil in a wok over medium-low heat. Add the doubanjiang and fry, stirring constantly, for 3–5 minutes. The dish lives or dies here: the paste must be cooked long enough and at the right temperature for the oil to turn a deep, translucent red and the raw fermented smell to mellow into a rounded, fragrant heat.

Add the roughly chopped douchi. Stir-fry for 30 seconds until the black beans are fragrant and have absorbed the red-stained oil.

4
Add the minced garlic and ginger. Stir-fry for 30 seconds until their raw sharpness gives way to a warm, aromatic bloom.

5
Add the ground pork. Break it up continuously against the wok. Cook until no pink remains and the meat has taken on the colour of the surrounding paste.

6
Add the Shaoxing wine and light soy sauce. Stir to combine. The sharp alcohol note from the wine should rise and begin to dissipate within seconds.

7
Pour in 200 ml of hot chicken stock and bring to a simmer. The liquid should be lively but not boiling hard — small, steady bubbles breaking the surface.

Slide the blanched tofu into the wok. Do not stir with a spoon; swirl the wok gently to move the tofu and coat it in the sauce. Simmer for 5 minutes. The tofu will absorb colour from the paste and the sauce will reduce slightly.

9
Add the cornstarch slurry in a thin stream, swirling the wok continuously. The sauce will tighten and cling to the tofu within 30–60 seconds; it should coat a spoon with a glossy, lightly bound consistency rather than pooling freely.

Add 2 tablespoons of chilli oil and stir gently to incorporate. The surface of the dish will take on an additional sheen of red.

Transfer immediately to a serving bowl. Scatter 1 teaspoon of freshly toasted and ground Sichuan pepper evenly over the surface, and finish with a further drizzle of chilli oil. Serve at once — the numbing tingle of the pepper should be perceptible from the first breath over the bowl.
