Radish kimchi or kkakdugi is another classic kimchi and popular side dish just like napa cabbage kimchi. There are actually a couple different versions of kkakdugi and this is the most popular version made with diced Korean radish. Enjoy it with Korean soups like samgyetang (Korean ginseng chicken soup) and seollentang (ox bone soup), but it's also commonly paired with jajangmyeon (Korean black bean noodles) and japchae (Korean glass noodle stir fry).
