This is a recipe for a basic napa cabbage kimchi. I have been making different kinds of kimchi for the past several years. It has taken several batches to find the right combination that my family likes. While it is much easier to just buy it from the korean market, there is nothing like homemade kimchi that is made with love and care. This is a rough recipe. Making kimchi is a method, not a strict recipe. Also, please note that it is important to find the best ingredients you can find. Mediocre ingredients lead to mediocre results. I find that the overnight salting is less wasteful and keeps the kimchi crunchier longer. It sounds like it takes a long time, but active prep time is probably about 1 to 1 1/2 hours since the cabbage does a lot of the work while you are sleeping.
