First, buy fresh Chinese cabbage, remove the poles, leave all the leaves, expose them to the sun, then prepare a vat, dry it, blanch it in a pot, and take it out after the leaves turn green slightly. Take it out and put it on a shelf to control the moisture. After the vegetables are cold, they can be piled up layer by layer in the prepared shoulders until they are more than ten centimeters above the steel mouth, and a big stone is placed on them, just like this for about a month.
This is what people used to do. Now everyone wants to eat pickled fish, basically they buy their own fish, then go to the supermarket to buy pickled cabbage packets, and pour them all in after direct fire. In fact, this taste is far less than that of sauerkraut when they were young. In order to make money, these businesses must not have enough pickling time, so there will be a lot of nitrite, which is carcinogenic, so everyone should try to eat less of this pickled product. It is ok to use it occasionally to stimulate appetite, but it is recommended not to use it for a long time, because it is a pickled product after all, and it is easy to cause cancer if you eat too much. I think people's health awareness is still quite high now, and it is rare to see people eat these things, such as pickled radish, pickled sauerkraut and pickled beans, which we ate every day when we were young.
