FROM: SUSHI CHEF
First of all the fish has to be fresh and stomach part is the best. You also need a really sharp knife and when you slice the fish it has to be one cut and all the way through.
for the rice you need Japanese rice and a bit more water than usual when you cook them in a rice cooker after that you need to mix the rice with a bit of Japanese Vinegar and hot sake. Don't press the fish to hard agaist the rice just put it on or gently press. Real Japanese soy sauce and a little Wasabi that is powder, mix it with water then put it in soy sauce. Then you don;t need to go to restaurant for sushi. For the fish anything is fine as long as it is fresh. Recommended: Hamachi (Yellow Tail), Toro ( Fatty Tuna), Sake ( Salmon ) and Uni ( Sea Urchin )
Thank you and enjoy
