First cook the rice - Wash the rice to remove excess starch until the water stays clear. Cook according to the instructions.
Transfer the rice to a bowl and let it cool down. Once cool, add the salt, sugar and brown rice vinegar and give it a mix.
Cut up an avocado, remove the pit and cut it in slices. Take off the peel then.
Form little rolls with the rice.
Cut the nori sheet into strips with a scissor.
Put the avocado slices (I broke them simply apart to fit better on the rice) onto the rice rolls and add the nori strips. You can wet the endings of the nori to make it stick together.
Sushi is best served with Pickled Ginger (Gari). Enjoy!
