Gather your bamboo mat and wash it off to make sure it’s completely clean. Find a cleaned, open space on your counter and put your mat down. Place one of your seaweed wraps on your bamboo mat. After washing and wetting your hands, place a thin layer of your rice mixture onto your seaweed slice. Press the layer of rice into place, and then place some of your add-ins into the middle of the rice. Use the mat and roll over your ingredients, pressing gently for the rice to form into a roll. Continue this until you run out of seaweed slices or your add-ins.
