Hosomaki is a type of sushi that consists of rice and various fillings wrapped in a sheet of nori, which is a type of seaweed. Typically, hosomaki is smaller in size compared to other sushi types, making it easy to eat in one bite. Common fillings include cucumber, tuna, and avocado. The preparation of hosomaki involves spreading sushi rice on a sheet of nori, placing the filling in the center, and rolling it tightly. Once rolled, the sushi is sliced into bite-sized pieces. Hosomaki is often served with soy sauce, wasabi, and pickled ginger for added flavor.
