One of the most popular sushi type is the maki sushi, (巻き壽司) or ?rolled sushi?. Wrapped in Nori, the small rolls are generally formed with the help of a makisu, a bamboo mat.
Besides the Maki rolls there is the gently hand-formed nigiri sushi. For a great Nigiri (which means ?squeezed?) you need the right balance between the topping and the rice.
The gunkanmaki sushi is very similar to the Nigiri sushi: On top of a hand-formed clump of sushi rice goes the topping. Because the Gunkanmaki topping is usually very loose, everything is wrapped up in a Nori strip.
