Recipe adapted from Epicurious and the San Francisco Chronicle (links below).
I couldn’t find chili powder so I used some Thai chili paste, which made the kimchi a bit murky. If you can, try to find the Korean chile powder. I added a scant teaspoon of Mexican chile powder for color. Even though my arm was killing me from carrying home all that pork, I was a trooper and hand-chopped all the garlic and ginger. But I think it could also be done in a blender or food processor.
Storage: Many advise to eat the kimchi within 3 weeks. After that, it can get too fermented.
