There are three main types of sushi, nigiri-zushi, which is vinegared rice hand-formed into oval shapes and topped with various raw and cooked seafood, maki-zushi which is vinegared rice combined with seafood and vegetables then wrapped in an edible seaweed called nori and sliced into rounds, and chirashi-zushi which is made on a plate and very much resembles rice cake. Nigiri-zushi is quite finicky to make at home and we tend to eat this type of sushi at Japanese restaurants and sushi bars. Maki-zushi and chirashi-zushi, on the other hand, is far easier to prepare in your own kitchen and the taste of these delightful morsels has left many with an addiction for life. This Maki-zushi recipe requires a sushi mat for rolling.
