Get a spicy cabbage. Radish is usually made of a clay pot, and then cover it with a container. The interface between the container and the jar is sealed with water.

Tool: A special pottery pickle jar. The unglazed jar outside is called a crock, and the glazed jar looks better. The jar mouth protrudes, and there is a circle of concave trays (that is, water tanks, which can hold water) around the jar mouth. The buckle bowl can seal the jar mouth, which can accelerate the fermentation of kimchi and produce a lot of lactic acid in the absence of oxygen. When making kimchi, fill the tray next to it with water and seal the jar to prevent air from entering. If there is no pickle jar, other containers can be used instead, but the container mouth should be large, tightly sealed and airtight. When I was a child, I went to buy pickle jars with my mother. She always looks carefully at the outside of the jar for sand holes and cracks, which is related to whether pickles will go bad. A kind of glass jar is popular now. This jar is beautiful, and plates of various colors can be seen from the outside. This is also a means to attract customers' attention in restaurants.
