This is a classic dish from Sichuan cuisine, renowned for its unique "fish-flavored" (Yuxiang) sauce. Despite the name, it contains no fish. The flavor is a complex, balanced blend of salty, sour, sweet, and spicy notes, relying heavily on chili, ginger, garlic, sugar, and vinegar. The dish consists of shredded pork stir-fried with vegetables (like wood ear mushrooms or bamboo shoots) and coated in the glossy, aromatic Yuxiang sauce.
