My father was stationed in Korea once upon a time and brought home a taste for Kimchi / Kim Chee.
My mother did make it a few times but from her description it sounded very complicated, and something no one should try without first getting a certification in Kim Chee Preparedness.
So when I no longer lived close to an Asian Market with gallon jars of it for a decent price, I learned either to do without, or pay $5 for a tiny little jar that would last me a week if I resisted the urge to eat it daily.
Then I got the book "Wild Fermentation" by Sandor Ellix Katz, and have been making delicious Kimchi easily, ever since.
Step 1: Assemble tools and ingredients
At its most basic, kimchee is chinese cabbage (can use napa, pac choi, or any chinese cabbage) fermented with garlic, pepper, salt, and ginger. Other ingredients such as daikon (or other radish), carrot, scallion / green onion or other onion, fish (in the form of dried crumbled fish, fish broth or fish sauce, or Hondashi fish broth powder), and even seaweed, are commonly used depending on preference.
Here I show Kosher Salt, scallions, daikon, fresh ginger, hondashi powder, dried pepper flakes specifically for making kimchee, fresh garlic, carrot, and a very large head of pac choi /bok choy.
You will also need a sharp knife, a large nonreactive mixing bowl, a smaller nonreactive mixing bowl, and glass or stoneware jars or crocks to hold the finished product.
You will need anywhere from several hours, to overnight, to soak the fresh chopped veggies in salt solution, and then anywhere from 5 days to 2 weeks to ferment your kimchee depending on how warm the room is, how much salt to vegetables, and whether you had leftover kimchee "juice" to jump-start the fermentation with.
For those who want measured quantities either to follow, or to get a ballpark idea of what the proportions are:
For roughly two quart jars:
2 lbs chinese cabbage
1 whole daikon radish or several red radishes
1 to 2 carrots
onions and/or leeks, bunch of scallions, or shallots... as many or few as you like.
6-8 cloves of garlic, or as many as you like... your love of garlic is the only limiting factor
5-6 tablespoons of grated ginger, or grate up a 4 inch piece... again, more to taste if you like it especially
Seaweed if you like, but I didn't use it in this recipe
3 tsp. hondashi japanese fish broth powder ( or a handful of dried bonito, crumbled)
Brine will be 4 cups of water to 4 tablespoons of salt. If this isn't enough to cover the fresh veggies, then double the brine recipe.
