1. Wash the mustard a day in advance and let it dry slightly
2. Pour into the container, add vinegar, white vinegar, rice vinegar, and old vinegar. You can add more if you like
3. Pour boiling water evenly on the mustard greens
4. The boiling water should be darker than the mustard greens
5. Cover the lid and leave it for 3-5 days. The longer the time, the more sour you will be.
6. Take out the wringing water. This time I marinated it for 4 days. The taste is sour and very delicious. When you want to eat it, wash it with clean water, wring it out and chop it to fry. It is very good for serving.
Tips:It can be washed and stored in cold storage, but try not to be too long. It is easy to marinate. Just marinate for one or two days.
