Jia Chang Cai (家常菜) – Weeknight Dinners That Earn Their Place
Stack the pressed tofu and slice the pork shoulder into matchsticks before the oil smokes in the carbon-steel wok, because the secret lies in da shui, the technique of vigorously beating water directly into the lean meat before it hits the heat. This step keeps the pork tender and springy—which, combined with the patience to properly brown the pressed tofu and a final splash of Kong Yen black vinegar, delivers a complex dinner in under twenty minutes. Turn the exhaust fan on high and keep the spatula moving.
Before you start
Prep and dry the tofu.
Even extra-firm pressed tofu holds lingering moisture. Pat the block completely dry with paper towels before slicing so it sears properly in the wok rather than steaming.
Ingredients
- pork shoulder or pork loin8 oz
- five-spice pressed tofu8 oz
- scallions2 med
- garlic3 med cloves
- Fresno chili or jalapeño1 med
- neutral cooking oil3 tbsp
- cold water2 tbsp
- soy sauce2 tbsp
- Shaoxing rice wine1 tbsp
- ground white pepper1/4 tsp
- cornstarch1 tbsp
- neutral cooking oil1 tsp
- oyster sauce1 tbsp
- granulated sugar1 tsp
- water2 tbsp
- Taiwanese black vinegar1 tbsp
- toasted sesame oil1 tsp
Method
- 01
Massage the pork with the liquid marinade ingredients.
In a bowl, vigorously mix the pork, 2 tablespoons cold water, 1 tablespoon soy sauce, rice wine, and white pepper. Massage in a circular motion with your fingers for about 60 seconds until the meat absorbs all the liquid, plumps up, and becomes slightly sticky. Do not add salt here, as it draws moisture out.
- 02
Seal the meat with starch and oil.
Once the water is fully absorbed, mix in the cornstarch to form a thin paste over the meat. Fold in 1 teaspoon of neutral oil to lock in the moisture and lubricate the pieces so they don't clump in the wok. Let it rest for 15 minutes.
- 03
Whisk the stir-fry sauce.
In a small bowl, whisk 1 tablespoon of soy sauce, oyster sauce, sugar, and 2 tablespoons of water until the sugar dissolves. Keep the black vinegar and sesame oil separate for finishing the dish.
- 04
Sear and brown the pressed tofu.
Heat a large skillet or wok over medium-high heat with 1 tablespoon of neutral oil. Spread the tofu matchsticks in a single layer and let them sear undisturbed for a minute. Toss and shallow-fry for 3 to 4 minutes until the edges of the tofu are golden and slightly scorched. Remove the tofu to a plate.
- 05
Flash-fry the pork to lock in the texture.
Return the wok to high heat and add the remaining 2 tablespoons of oil. When shimmering, add the pork. Let it sit for 15 seconds to sear, then rapidly stir-fry for 1 to 2 minutes just until the outside turns pale but the inside is still slightly raw. Transfer immediately to the plate with the tofu. Working in batches prevents the meat from stewing in a home kitchen.
- 06
Bloom the aromatics and build the dish.
In the residual hot oil, stir-fry the garlic, chili, and the white parts of the scallions for 15 seconds until highly fragrant. Return the tofu and pork to the pan. Pour the reserved sauce around the perimeter of the wok to create steam, then toss vigorously for 1 minute until the sauce reduces and clings tightly to the ingredients.
- 07
Finish with vinegar, sesame oil, and scallion greens.
Turn off the heat. Immediately toss in the green parts of the scallions, splash the Taiwanese black vinegar and toasted sesame oil around the edges of the hot pan, give it three final tosses, and immediately transfer to a serving plate.
Notes
The Black Vinegar Rule
Do not substitute Chinese Chinkiang vinegar if you cannot find Taiwanese black vinegar. The Taiwanese version evolved from Worcestershire sauce and is fruitier and sweeter. If you do not have it, mix 1/2 tablespoon of standard Worcestershire sauce with 1/2 tablespoon of unseasoned rice vinegar for an exact flavor match.
The Da Shui Technique
Beating water into lean pork before cooking ensures it stays impossibly silky and tender instead of turning rubbery in a hot pan. Adding a layer of oil at the very end of the marinade process seals that hard-earned moisture inside.
