Hello, white radish kimchi, as long as the materials you mentioned are soaked in radish, will they be sour and brittle in a few days? Where does the sour taste come from?
Use cold boiled water, add some salt, pepper, star anise, red pepper and so on. Add some green and yellow vegetables to taste. Cut the white radish into strips, put them together in the pickle jar, seal them for about 1 week, and they will be sour and can be eaten for more than ten days. Sour taste is produced by natural fermentation of vegetables. After pickling for a month, the teeth will be sour! Be careful!
