Common toppings include raw fish like salmon and tuna, as well as cooked options like shrimp and eel. Vegetables such as avocado and cucumber are also popular, adding freshness and texture. In addition to fish and vegetables, sushi toppings can include pickled ginger and wasabi for added flavor. Some sushi varieties feature unique toppings like fish roe or tempura flakes, enhancing the overall taste and presentation. Each topping contributes to the diverse experience of enjoying sushi.
