Amazing dish! It was easy. I did make my own Torgarashi spice because I didn't want to go to the store and just used what I had at home. After a couple googles I decided to grind in my spice grinder: 1T black pepper corns, 1.5 T fresh orange peel, heaping 1T crushed red pepper, 1.5T dried seaweed, 1t sesame seeds (I used white), 1t black poppy seeds, 1.5t minced garlic. I doubled the amount of Torgarashi in the recipe equaling heaping 1t because what I ground probably wasn't as fine of a grind as store bought spices. Followed everything else as per the recipe states. So yummy! Took only 30m! Will make again and have added to my recipe stash.
I've been cooking this for years, still a favorite.
