We've been making our tour around the sushi bar these days, covering different kinds of fish. Though most of us adore the silky smooth raw fish, let's not forget that the word "sushi" actually refers to the sweet, vinegared rice. It's not about the fish (that's technically, but I too, would cry a Pacific Ocean if I had to eat sushi without the fish).
Since it's not just about the fish, that means there are some vegetarian-ish options available at the sushi bar. I learned all about these, as well as the "cooked" fish in sushi during my sister's pregnancy. One of the most common non-fish options is tamago, which is a sweetened egg omelet. The omelet is cut into the same shape and size as sushi fish, and placed on the rice.
We've already talked about cucumber rolls, kappa maki, in a previous post. However, the use of vegetables in rolls doesn't stop there. A sushi chef can basically make a roll with any one or combination of vegetables, though it seems the big three are asparagus, cucumber, avocado. However, I have also seen more interesting vegetables. Kanpyo is dried gourd, shiso are the leaves that look like large mint leaves (often used for garnish as well), and ume, a Japanese plum that is sometimes pickled or salted.
