Zha Jiang Mian炸酱面

Combine the diluted yellow bean paste, yellow soybean paste, and sweet bean sauce in a large mixing bowl. Stir thoroughly until smooth and homogenous. Add 300–400g of hot water and stir again until fully incorporated. Set aside. (Tip: thinning the sauce before frying makes it easier to control consistency.)

Separate the pork belly into fatty and lean portions. Dice each into roughly 1 cm cubes. Toss the lean pork with a splash of huangjiu and set aside to marinate briefly. (Tip: chilling the meat in the freezer for 15 minutes makes it firmer and easier to dice evenly.)

Mince the ginger finely. Roughly chop the scallions and divide into two equal portions — one portion goes in early with the fatty pork, the other is reserved to add at the very end.

Heat about 200g of cooking oil in the wok over low heat. Add the Sichuan peppercorns and fry gently, stirring occasionally, until fragrant and the peppercorns just begin to color (about 2 minutes). Remove and discard the peppercorns immediately — do not over-fry or they will turn bitter. (The seasoned oil can be reserved: once the jiang is nearly done, pour off the excess oil and refrigerate as 'lao you' to use in future batches or for frying fish and vegetables.)

Increase heat to high. Add the marinated lean pork to the hot peppercorn-infused oil. Stir-fry briskly until the pork just changes color on all sides — about 2 minutes. Remove immediately and set aside. Do not cook through; the lean pork will finish cooking when it returns to the sauce later.

Add the diced fatty pork to the same wok over medium heat. Stir-fry until the fat renders visibly and the pork cubes begin to shrink and turn golden at the edges. Add the first half of the chopped scallions and stir to combine. The rendered pork fat will become the base of your fried sauce — the more thoroughly it renders, the richer the final sauce will taste.

Pour the prepared sauce mixture into the wok. Stir to combine with the pork fat and scallions. Bring to a full boil over high heat, then immediately reduce to low heat. The sauce will bubble vigorously at first — keep stirring from the bottom to prevent scorching.

Simmer over low heat, stirring continuously from the bottom of the wok. The sauce will gradually lose moisture — steam rising from the surface will slow and then stop. As it reduces, the color deepens from reddish-brown to a rich dark brown. Continue simmering until the sauce coats the back of a spoon and the excess water has evaporated (about 15–20 minutes total from when you poured in the sauce).

While the fried sauce is simmering, bring a separate large pot of water to a boil. Cook the fresh or dried noodles according to package instructions until just done — they should be cooked through but still have slight bite. Drain well.

Place drained noodles in a bowl. Spoon over a generous amount of fried sauce. Toss until the noodles are evenly coated — you can mix any vegetable toppings in at this stage, or arrange them on top after mixing. Serve hot.
