Yes, I took it out of the package I bought at Tokyo Fish Market, and sliced it with the sashimi knife. Voila. Home cooking! I made the furikake the same way. I opened the lid and sprinkled it all by myself. As for the wasabi, that I really prepared by taking the powder and mixing it with water, at home, all by myself. (The prepared stuff in the tube has too much extra junk in it). One day when I'm feeling rich, I'll buy some fresh wasabi root.
