- Cut the watermelon rind into thin strips about 2 inches long. Place the rind strips in a large bowl and toss with the salt. Let sit for 1 hour.
- For a less salty kimchi, rinse the rind and dry on paper towels. If you want more salt, no need to rinse. In a large bowl, combine the rind with the chives, ginger, garlic, gochugaru (add more or less gochugara depending on how spicy you like it) and honey. Stir to combine.
- Transfer the kimchi to a jar or another glass container with a tight fitting lid. Leave the kimchi out at room temperature for 2 days, then move to the refrigerator. The kimchi should be ready to use after about 5 days total.
