After the fall of Tsarist Russia, the recipe was popularly served in the hotels and restaurants of China before the start of World War II. Russian and Chinese immigrants, as well as US servicemen stationed in pre-Communist China, brought several variants of the dish to the United States, which may account for its popularity during the 1950s. It came to Hong Kong in the late fifties, with Russian restaurants and hotels serving the dish with rice but not sour cream.
