To ferment:
Transfer the kimchi to a glass jar or a plastic container and keep it at room temperature for a couple of days.
*tip: When it ferments, it will smell and taste sour, and the color of the greens will change to olive green.
When the kimchi ferments, scoop some kimchi juice from the bottom of the container to the top so that the top layer of the kimchi won’t dry out and your kimchi will be juicy.
