Cantonese-style sweet and sour shrimp is a classic dish that is tangy, sweet, and savory. The shrimp is coated in a light batter and deep-fried until crispy. It is then tossed in a sauce made with vinegar, ketchup, sugar, and soy sauce. The result is a dish that is both crispy and saucy, with a perfect balance of flavors. Serve it with steamed rice and stir-fried vegetables for a complete meal.
