Types of sushi

Nigiri Sushi

Nigiri-zushi (hand-formed sushi). This consists of an oblong mound of sushi rice that is pressed between the palms of the hands, sometimes with a speck of wasabi, and a slice of fish called neta draped over it. Certain fish is typically bound to the rice with a thin strip of nori, most commonly tako (octopus), unagi (freshwater eel), anago (sea eel), ika (squid), and tamago (sweet egg). Nigiri is generally served in pairs.
___________________________________________________________________ Maki Type

Maki-zushi (rolled sushi) a cylindrical piece, formed with the help of a bamboo mat, called a makisu. Makizushi is generally wrapped in nori, but can occasionally be found wrapped in a thin omelette, soy paper, cucumber, or parsley. Makizushi is usually cut into six or eight pieces, which constitutes a single roll order. Above is the Boiler Maki Roll.
___________________________________________________________________ Etiquette
Sushi can be eaten either by hand or using chopsticks, although traditionally nigiri is eaten with the fingers because the rice is packed loosely so as to fall apart in one's mouth, and would disintegrate on chopsticks.Condiments (soy sauce, wasabi, and pickled ginger) are used as desired.
