Sweet and Sour Pork
甜酸肉·(tián suān ròu)
The Iconic Mains: Chef's Specialties
The folded paper carton is heavy in the hand, leaking one drop of red syrup onto the passenger seat on a rainy Tuesday at 7 p.m. We aren't trying to reinvent takeout or chase some elusive purist authenticity; we are building the absolute best version of the meal you've ever tasted, where the pork batter shatters under a hot wave of vinegar and canned pineapple chunks. Fry the pork twice, forget the delivery fee, and eat it straight from the box.
Before you start
Set up a landing zone.
Place a wire rack over a rimmed baking sheet. This allows the oil to drain and keeps the pork from getting soggy underneath during the crucial resting phase between fries.

Method
- 01
Massage the pork with soy sauce, Shaoxing wine, baking soda, salt, and white pepper until fully absorbed.
This is the velvet technique, essential for takeout-level tenderness. Let it marinate at room temperature for at least 30 minutes, but do not exceed an hour, or the baking soda will break down the meat too aggressively.
- 02
Mix the egg white, cornstarch, flour, and cold water directly into the marinated pork.
Use your hands to combine everything until a thick, sticky batter forms that clings stubbornly to the meat like wet paint. If it feels too dry or crumbly, add water one tablespoon at a time.
- 03
Whisk the vinegar, ketchup, sugars, pineapple juice, soy sauce, and Worcestershire sauce in one bowl, and prepare a separate cornstarch slurry in another.
The slurry is simply the 1 tablespoon of cornstarch mixed with 2 tablespoons of cold water. Keep it right next to the stove.
- 04
Fry the battered pork in 350°F oil for four to five minutes until pale golden and cooked through.
Drop the pieces into the heavy-bottomed pot or wok one by one so they don't fuse together. Work in batches so you don't crowd the pan. Move them to a wire rack to rest.
- 05
Increase the oil temperature to 390°F and flash fry the rested pork for 60 to 90 seconds.
This violent thermal shock evaporates the surface moisture, locking in a deep mahogany crust that will shatter when you bite into it. Listen to the pork; it will sound hollow as you move it. Transfer back to the wire rack.
- 06
Empty the wok, heat a tablespoon of fresh oil, and blister the garlic, ginger, onion, bell peppers, and pineapple.
You want fierce, high heat to unlock the essential oils of the aromatics and put a quick char on the vegetables without turning them to mush. Stir-fry for about 60 seconds.
- 07
Pour in the sweet-and-sour liquid, bring it to a rapid rolling boil, and aggressively stir in the cornstarch slurry.
This is the takeout trick for a perfect glaze. The sauce must be violently boiling when the slurry hits it to instantly transform it from a cloudy red liquid into a brilliant, transparent syrup.
- 08
Turn off the heat, dump the double-fried pork into the wok, and toss it massively four or five times.
Get every piece lacquered in the sticky glaze and get it immediately out of the pan. Serve immediately with freshly steamed white jasmine rice.
Notes
Pork shoulder is non-negotiable.
Do not substitute lean pork tenderloin. The intramuscular fat in the pork shoulder butt is absolutely essential to survive the high heat of the double fry without drying out.
The science of the clear sauce.
Adding cornstarch slurry to a warm or simmering sauce creates a chalky, cloudy gravy. Hitting it at a rapid, rolling boil forces the starch granules to gelatinize instantly and uniformly, resulting in that iconic jewel-like restaurant glaze.
