Sweet and sour pineapple pork, also known as Fènglísū ròusī in Chinese, is a delicious and popular dish that combines the tangy flavors of pineapple with tender pieces of pork. To make this dish, start by marinating the pork in a mixture of soy sauce, ginger, and garlic. Then, stir-fry the marinated pork until it is cooked through and set it aside. In the same pan, sauté onions, bell peppers, and pineapple chunks until they are slightly caramelized. Next, add a sweet and sour sauce made from a combination of pineapple juice, vinegar, ketchup, and sugar. Allow the sauce to simmer until it thickens, then add the cooked pork back into the pan and toss everything together. The result is a mouthwatering dish with a perfect balance of sweet and tangy flavors. Serve the sweet and sour pineapple pork over steamed rice for a complete meal that will satisfy your taste buds.
