One of the best soups I've had was served at the Animal Kingdom Lodge. I've been searching for a similar recipe for years and I think this is going to be it!
Spicy Dandan style meat sauce over rice. You can pretty much substitute some of ingredients for your taste. I often use chili bean paste, peanut butter, sesame paste (or sesame seeds and oil), hoisin sauce. These are probably the he most important. For the pickled mustard, maybe just add more onions.
This is a no waste recipe. We buy King Salmon Sashimi scraps and bake them to eat. The meat is scraped off gently before serving and we set the skins aside for the furikake.
