Nigiri

Nigiri* is a kind of sushi where fish, shellfish, or other toppings (neta) are placed on a small, hand-formed mound of rice (shari). It's also known as Edomae sushi. The term "nigiri" comes from the action of forming the sushi by holding and shaping the neta atop the shari.

*"Nigiri" is derived from the verb "nigiru", which means "to hold".
