Rinse your seaweed in cold water for 15 minutes. Soak in cold water for as long as you can possibly wait and then some. Make sure you rinse the seaweed again before using it. Brown seaweed stems come packed in salt and if you don’t rinse or soak you’ll have an over salted salad.Mix together the dressing ingredients. Toss with the seaweed. Enjoy!**You can find seaweed packaged in salt in most Korean grocery stores. They’re usually labelled “salted brown seaweed stems.â€
