What's your favorite sweet and sour taste?

I come from Shanghai, and I like peppers very much. Cuisine, sweet and sour, is taste, which is the reason why various cuisines and factions exist. Every dish has a flavor that must exist. Braised pork in Shanghai is sweet but not greasy. Fish with Chinese sauerkraut in Sichuan is sour and delicious. Northeast stews, fresh soup, chicken with bean sprouts and so on are all delicious. Stir-fry a bitter gourd What is delicious and not bitter? Xinjiang roast leg of lamb is spicy, not sandalwood. The oil dripped on the firewood. It smells good! The stinky tofu in Shanghai Chenghuang Temple stinks. It's delicious! Therefore, I am never picky about dishes. I keep the ingredients fresh, the chef cooks them, and I like the taste of every dish. But my favorite is pepper.
