It is a mistake to believe that the birthplace of Korean carrots is Korea. The appetizer was invented in the USSR while trying to prepare kimchi - cabbage with spices. The Chinese cabbage needed for the recipe was difficult to obtain, so it was replaced with carrots. Over time, carrots replaced Chinese cabbage in salads. For Korean carrots with onions, you need to take juicy, sweet root vegetables. You can use any onion: onion, red or white. Experiments with spices are welcome.
