To make the sushi take your bamboo sushi mat and place a sheet of nori on top. (For smaller maki cut the nori sheet in half)
Make sure you have a small bowl of water to dip your fingers in before you touch the rice. (Do this regularly between touching the rice, it's sticky!)
Spread some sushi rice over the nori sheet (leave about a 2cm gap border on the edge facing you), do this gradually using a little rice at a time, it should be just under a cm thick (less if you want).
Place some filling in the centre of the rice in a line (whatever you fancy... prawns & avocado, salmon etc)
Now for the rolling! Using the sushi mat, start rolling up the ingredients away from you, while keeping the roll tight. The moisture from the rice will help it stick together.
Make sure you firm the roll up with the mat, press fairly hard to make sure it's tight.
Remove the sushi mat from around your roll.
Use a slightly wet & very sharp knife to cut through your roll and into slices.
Serve up with some wasabi, pickled ginger & gluten free soy sauce to dip.
Enjoy!
