First, prepare a pickle jar. There is a jar specially used to make sauerkraut, and you have to buy a dish called green vegetables in Sichuan, which is also specially used to make sauerkraut. After preparing these two things, there is one more important thing. If you want to make authentic Sichuan-style sauerkraut, you have to ask Sichuanese who have kimchi at home to serve 2 bowls of kimchi water, so that the pickled vegetables will be more fragrant. If you can't get it, you can only use salt water instead. Salt should be boiled. It's cold. You should start putting things in the jar. Put the cold salt water in the jar first, and then put the vegetables in it. At first, soak them less. The more times you soak, the more water you will get. Then, add ginger, pepper, pepper, cover and leave for a few weeks, and Sichuan-style sauerkraut can be baked.
