Step 1: Prep and Marinate the Fish
Clean the fish and pat dry.
Make diagonal slits on each side to allow flavors to penetrate.
Rub with Knorr Liquid Seasoning (or soy sauce), then season with salt and pepper.
Let it marinate for 15–30 minutes.
Step 2: Dredge and Fry
Lightly coat the fish in flour, shaking off any excess.
Heat oil in a wide pan over medium heat.
Fry the fish for 4–5 minutes per side until golden and crisp.
Drain on paper towels and set aside.
Step 3: Sauté the Aromatics
In a clean pan, heat 1 tbsp oil.
Sauté onion, garlic, and ginger until fragrant and slightly golden (about 2–3 minutes).
Step 4: Make the Sweet and Sour Sauce
Add vinegar, ketchup, sugar, and water. Stir to combine.
Bring to a boil, then add carrots, bell peppers, and pineapple chunks (if using).
Simmer for 2–3 minutes until vegetables are tender-crisp.
Step 5: Thicken the Sauce
Mix cornstarch with water to create a slurry.
Slowly add to the pan while stirring constantly until sauce thickens and becomes glossy.
Taste and adjust sweetness or tanginess as needed.
Step 6: Assemble and Serve
Place the fried fish on a serving platter.
Pour the sauce and vegetables over the top.
Garnish with chopped spring onions or extra pineapple.
Serve hot with steamed rice.
