Haoyou shengcai (lettuce in oyster sauce)

Lettuce is blanched or stir-fried over high heat for about 20 seconds and dressed with a sauce of oyster sauce and garlic.

Haoyou shengcai is a Cantonese dish of lettuce leaves quickly blanched or stir-fried over high heat and dressed with oyster sauce, usually with garlic. It is popular in Chinese restaurants. Shengcai sounds like the words for making money, so the dish is eaten at Chinese New Year for luck. Oyster sauce is linked to Nanshui in Zhuhai, Guangdong. Two accounts date the seasoning: a 2025 report links it to a company's founding in 1888, while another places oyster sauce production in China no later than the mid-1870s. These dates concern the seasoning, not the dish; no dated record of the dish itself was found.
