A sushi roll is a popular Japanese dish that consists of vinegared rice combined with various ingredients, such as seafood, vegetables, and sometimes tropical fruits. The ingredients are typically rolled in a sheet of nori, which is a type of seaweed, and then sliced into bite-sized pieces. Sushi rolls can be served with condiments like soy sauce, wasabi, and pickled ginger. There are many types of sushi rolls, including the California roll, which features imitation crab, avocado, and cucumber, and the spicy tuna roll, made with raw tuna and spicy mayonnaise. Sushi rolls can be enjoyed in restaurants or made at home, offering a versatile and customizable dining experience.
