Yellow pickled radish, also known as 喖 muki, is common in Japanese and Korean cuisine, used to make side dishes, or used to make kimbap. The taste is sour, sweet and crisp, adding to the taste of other foods. It's usually sold at the sushi counter in supermarkets for about 15 yuan a piece, and you can cut it yourself when you go home. There are thin strips cut into Korean stores, about 12 yuan per pack, and can be used to make kimbap. However, most of the commercial products use pigments. You can save money and be healthy by making them at home.
