Method
- Marinate the pork in Shaoxing, soy, the beaten egg and a tablespoon of cornstarch for 15 minutes. The egg gives the crust its crackly puff.
- Roll each cube in dry cornstarch until thickly coated. Pat off excess; the coating should be uneven, almost lumpy — this is what gives the rough, crisp texture once fried.
- Heat oil to 170°C. First fry: lower the pork in batches and fry four minutes until pale gold. Lift onto a rack and rest five minutes — the cooling step is what allows the second fry to crisp without burning.
- Second fry: increase oil to 190°C. Return the pork in batches for one minute until deeply golden and crackling. Drain on the rack.
- In a clean wok with 1 tbsp oil, stir-fry the onion 30 seconds, then peppers 30 seconds. Add pineapple. In a bowl, mix vinegar, sugar, ketchup, soy and 100ml water; pour into the wok and bring to a boil.
- Whisk in the cornstarch slurry. The sauce thickens to a glossy red coat in fifteen seconds. Add the fried pork and toss vigorously for ten seconds — no longer, or the crust softens. Slide onto a plate; serve immediately with rice.

Cultural Note
The dish's Cantonese name — gū lū ròu, 'gurgling pork' — supposedly mimics the sound of a hungry diner's stomach. The pineapple is divisive: traditional Cantonese versions use the fruit, while Hong Kong versions sometimes drop it for a purer sweet-sour profile. The dish travelled in the late nineteenth century with Cantonese migrants and became the staple of Western Chinatowns; the ketchup-heavy versions abroad evolved from limited access to vinegar styles. Rough, crackling crust and a sauce that pools rather than soaks is the marker.
