Place the rice in a sieve and rinse until the water runs clear. Leave to drain. Place it into a sauce pan, pour over the cold water place on a lid and bring to the boil (make sure it is a tight fitting lid, mine isn't so I have used cling film to seal it properly)

Bring it to the boil for 5 minutes. Reduce the heat after this and cook it for a further 10 minutes. Then leave the pan to stand for a further 10 minutes do not take the lid off.

Get a baking tray, then spoon on the rice so it is an even layer, add little by little the vinegar folding it in with a spoon, carry on doing this until the vinegar has all be absorbed. Leave it to cool the rice is now ready to be used for your sushi making.
