Start by preparing sticky sushi rice, then spread it over nori sheets, leaving an edge uncovered. Add fillings, such as cucumber, avocado, and crab, and roll tightly using a bamboo mat. Seal with water, slice carefully, and serve with classic accompaniments like soy sauce, pickled ginger, and wasabi. A perfect snack or meal, sushi rolls can be paired with miso soup or a seaweed salad.
