Nigiri is a type of Japanese sushi consisting of a small mound of vinegared rice topped with a slice of raw fish or seafood. The rice is typically hand-formed into an oval shape, and the topping can vary widely, including options like salmon, tuna, or shrimp. Traditionally, Nigiri is served with a small amount of wasabi between the rice and the fish, enhancing the flavor. It is often enjoyed with soy sauce for dipping. This sushi style emphasizes the quality of the ingredients, making it a popular choice among sushi enthusiasts.
