Clockwise from bottom are the essential toppings for Okonamiyaki (fish flakes, Okonami sauce, seawead flakes, and japanese mayonase). The okonami sauce is made of plums, apples, worcestershire sauce, sugar, vinegar and a number of other wonderfully asian tasting ingredients. It is similar to yakisoba sauce and tonkatsu sauce (bulldog sauce in America). The mayonase is different than american mayonase-It is smoother and thicker, and sweeter. The fish flakes are just what they sound like, dried flaked fish that japanese people consume by the megaton. The nori flakes are a little salty and absolutely essential.
