There are several types of sushi, with maki being one that you’re likely most familiar with. This type of sushi comes in a roll shape, usually cut into  6-8 bite-sized slices. They contain the filling surrounded by rice, all wrapped up in the sheet of seaweed. In comparison, to make avocado uramaki (the "inside-out" roll), the rice is outside the roll, with the seaweed and filling in the middle.
