1Prepare the Korean green chili peppers. Wash 500 grams of Korean green chili peppers thoroughly and pat them dry. Using a fork or a skewer, prick each Korean green chili pepper a few times to allow the pickling liquid to penetrate.
3Make the pickling liquid. In a medium pot, combine 250 grams of soy sauce, 250 grams of water, 100 grams of Korean malt syrup, 150 grams of rice vinegar, the sliced garlic cloves, sliced fresh ginger, 5 grams of dried kelp, and 10 grams of dried shiitake mushrooms. Bring the mixture to a rolling boil over medium-high heat.
