Remove the core from the 1500 grams napa cabbage and cut it into 3"x3" pieces. In a very large bowl or clean bucket, add the napa cabbage and toss with the ¼ cup sea salt.

Cover the cabbage with cold water. Put this in a room temperature place for 24 hours. This removes some of the excess water from the cabbage making it crunchier and it also begins the fermentation process.
The next day, put the 50 grams onions, 30 grams garlic, 15 grams fresh ginger, 65 grams apple, 3 tablespoons Saeujeot, 3 tablespoons cooked short-grain rice, 1 tablespoon myeolchijeot, and 2 teaspoons granulated sugar in a blender or food processor and process until you have a smooth paste.

In a medium sized bowl, add the 150 grams Korean radish, 150 grams carrot, 4 scallions, 35 grams garlic chives and ½ cup gochugaru along with the mixture from the blender. Put on some food-safe gloves and squish the mixture together with one hand. Taste the mixture and add more gochugaru if you want it spicier.

Drain the cabbage then return it to the bowl along with the seasoned vegetables. Toss the mixture together with your hands until everything is very well combined.
Your kimchi is edible right away, but it's best to let it ferment in a cool place for at least a week.
