- Kelp (or Kombu) stock is commonly used in Japanese and Korean cooking.
To make a quick kelp stock for this recipe, place half a strip of kelp (gently wipe clean first) and 2.5 cups of water into a small pot. Bring it to a boil, and let simmer for 5-6 minutes over low heat. The stock is ready to use when it is a light golden color. Remove the kelp (you can save it to make more stock later, or to use in other dishes).
