(Seems like I'm mostly blogging on Korean foods lately, by the way. I'm proud.)
I'm not gonna write down how to make them, since I have too many stuff I need to upload that I haven't uploaded yet, and it's also pretty self-explanatory. Just get the ingredients together and roll them up. It's as easy as that.
You can make the dipping sauce by simply mixing wasabi + soy sauce + vinegar.
