When I was a child, I had a lot of mustard at home. My mother always made pickles for me to eat. I can't finish buying too many today. So I used them to make pickles.
Step1:Wash the mustard. Heat a pot of water. It's hot. You don't need to roll it. Put the mustard in and blanch it. Don't blanch it for too long. It's OK.
Step2:Take it up and put it in a fresh-keeping box or something that can be sealed. Put in the water for blanching mustard. It's ok if you don't have mustard. It doesn't need too much.
Step3:You can eat it in a day or two. If you want to eat sour, please let it go for a long time
Cooking tips:The process of cooking must be oil-free and skillful.
