Cantonese-style sweet and sour shrimp is a popular dish that combines the flavors of tangy sweetness and savory umami. The shrimp is coated in a batter, deep-fried until crispy, and then tossed in a sauce made with vinegar, ketchup, sugar, and soy sauce. It is then stir-fried with bell peppers, onions, and pineapple for a colorful and delicious dish. Serve it over steamed rice for a complete meal.
