Sweet and sour pork loin is coated in a crispy batter and drenched in a bright vinegar-sugar glaze. Originating from Northeast China, this family favorite balances tangy, sweet, and crunchy textures in every bite.
Cut the pork loin into bite-size strips, pat dry, and season lightly with salt.
In a medium bowl, whisk eggs, then combine with cornstarch and flour to make a thick batter—whisk until smooth to avoid lumps.
Dip each pork piece into the batter, ensuring full coverage for extra crispiness.
Heat vegetable oil in a deep pan to 350°F. Fry pork pieces in batches for 3–4 minutes, turning once, until golden—do not overcrowd for even cooking.
Drain pork on a wire rack. In a saucepan, combine rice vinegar, ketchup, sugar, soy sauce, salt, and water. Simmer for 3–4 minutes, stirring constantly, until glossy and thick.
Toss crispy fried pork with the hot sweet and sour sauce, ensuring every piece is coated evenly. Serve immediately for maximum crunch.
