니기리즈시 is a type of sushi that features hand-formed rice topped with various ingredients, typically seafood. The rice is seasoned with vinegar, sugar, and salt, giving it a distinct flavor. Common toppings include tuna, salmon, and shrimp, but chefs often use seasonal and regional ingredients to create unique variations. This sushi style is known for its simplicity and emphasis on the quality of the ingredients. Unlike maki, which is rolled sushi, 니기리즈시 is served as individual pieces, allowing diners to appreciate the texture and taste of each topping. It is a popular choice in sushi restaurants worldwide.
