Ingredients

For the Pork

1 pound boneless pork shoulder or pork loin, cut into 1-inch cubes
1 teaspoon kosher salt
½ teaspoon black pepper
1 large egg
½ cup cornstarch
¼ cup all-purpose flour
Vegetable oil, for frying (about 3 cups)

For the Sweet and Sour Sauce

¾ cup pineapple juice (from canned pineapple)
⅓ cup granulated sugar
⅓ cup ketchup
¼ cup rice vinegar (or distilled white vinegar)
1 tablespoon soy sauce
1 tablespoon cornstarch

For the Stir-Fry

1 cup pineapple chunks (canned or fresh)
1 medium green bell pepper, cut into 1-inch squares
1 medium red bell pepper, cut into 1-inch squares
1 medium yellow onion, cut into chunks
1 tablespoon vegetable oil

Optional Garnish

Sliced green onions
Toasted sesame seeds

Step-by-Step Instructions

Prepare the Pork
Pat the pork cubes dry with paper towels. Season evenly with kosher salt and black pepper. Set aside while you prepare the batter.
Make the Batter
In a medium bowl, whisk the egg until smooth. Add the cornstarch and flour, stirring until a thick, sticky batter forms. Add the pork pieces and toss until each piece is fully coated.
Heat the Oil
In a deep skillet or Dutch oven, heat vegetable oil to 350°F over medium-high heat. The oil should be deep enough to submerge the pork pieces halfway.
Fry the Pork
Working in batches to avoid overcrowding, carefully add the battered pork to the hot oil. Fry for 4–5 minutes, turning occasionally, until golden brown and crisp. Transfer to a wire rack or paper towel-lined plate. Repeat with remaining pork.
Mix the Sauce
In a bowl, whisk together pineapple juice, sugar, ketchup, rice vinegar, soy sauce, and cornstarch until fully smooth. Set aside.
Stir-Fry the Vegetables
Heat 1 tablespoon vegetable oil in a large skillet or wok over medium-high heat. Add the onion and bell peppers. Stir-fry for 2–3 minutes, until slightly softened but still crisp.
Add Pineapple
Stir in the pineapple chunks and cook for 1 minute, just until warmed through.
Thicken the Sauce
Pour the prepared sweet and sour sauce into the skillet. Cook, stirring constantly, for 2–3 minutes until the sauce thickens and becomes glossy.
Combine and Finish
Add the fried pork to the skillet. Gently toss to coat the pork evenly with the sauce. Cook for 1–2 minutes, just until everything is well combined and heated through.
Serve Immediately
Remove from heat. Garnish with green onions or sesame seeds if desired, and serve hot.

Expert Tips & Variations

Professional Cooking Tips

Maintain oil temperature: Keep the oil close to 350°F for crisp, non-greasy pork. Too cool and the batter absorbs oil; too hot and it burns before cooking through.
Double-fry for extra crunch: For ultra-crispy pork, fry once at 325°F until cooked, then fry again at 375°F for 1–2 minutes before saucing.
Sauce consistency control: If the sauce thickens too much, add 1–2 tablespoons of water or pineapple juice to loosen it.

Ingredient Substitutions

Protein swap: Use chicken breast or thighs in place of pork with identical cooking times.
Vinegar options: Apple cider vinegar works well if rice vinegar isn’t available.
Sugar alternatives: Use light brown sugar for a deeper caramel note.

Dietary Variations

Gluten-free: Replace all-purpose flour with rice flour and use gluten-free soy sauce.
Lighter version: Skip battering and lightly pan-sear pork cubes instead, then toss with sauce.
Vegetarian: Substitute extra-firm tofu or cauliflower florets for pork, frying until crisp.

Serving Suggestions

Sweet and Sour Pork III is best served immediately while the pork remains crisp and the sauce glossy.

Classic pairing: Steamed white jasmine rice or fried rice absorbs the sauce beautifully.
Noodle option: Serve over lo mein or rice noodles for a heartier meal.
Fresh contrast: Pair with lightly sautéed bok choy or steamed broccoli for balance.
Family-style: Serve in a large platter at the center of the table with rice on the side.

The sweet, tangy sauce pairs exceptionally well with neutral starches, while the crunchy vegetables keep each bite lively and fresh.

Storage & Make-Ahead Notes

Refrigeration: Store leftovers in an airtight container for up to 3 days.
Reheating: Reheat gently in a skillet over medium heat. Add a splash of water to loosen the sauce if needed.
Make-ahead tip: Prepare and fry the pork up to 6 hours ahead. Reheat in a 375°F oven for 8–10 minutes before tossing with freshly made sauce.
Freezing: Not recommended, as the batter loses its crisp texture after thawing.
