What is in a Happy Roll Sushi?

This one I will answer with a briefcase full of sushi, of course! There is a clear connection between the sushi itself and its processing. In traditional sushi there is a raw fish roll (aki) paired with mayonnaise and prepared on a hotplate. The traditional preparation calls for the rice to be flipped several times so as to create the distinct colors on the exterior, but in the United States the term "happy roll" seems to be used to describe the thin, crisp, shortish roll that the sushi is served on.

In other words, what is in a happy roll sushi refers to the fact that it is not too thick or too thin - the basic concept behind the sushi is to have the lightest part of the fish exposed. Typically the inari, or sweet, sesame seed topping is included, but additional toppings such as kuromame (pickled white grapes), or (crusty seaweed) or spicy miso may be added. Traditionalists may also serve some rice cake as an added touch. In a Happy Roll, the sesame seeds are not visible; hence the term "Happy Roll."

What is in a happy roll sushi may appear to be a simple question; but when you think about it, the preparation itself reveals quite a bit about what is in a happy roll. Traditionalists may argue that binary and kuromame are the only two possible additions to the sushi and that using any more than that would be inappropriate. However, the range of ingredients used in sushi makes it impossible to say whether or not each combination is authentic. Some sushi chefs are willing to experiment and have even developed special ingredients such as California Roll to use with their sushi rolls. What is in a happy roll sushi?
