This dish definitely has the wow factor yet is so easy, even the kids can make them, although they may prefer tuna or chicken is popular in place of the salmon and salmon roe. Smoked salmon can also be substituted with sashimi salmon and a small spread of wasabi over the sushi rice to help clear the sinuses!
The Japanese believe a matching dinner set of 4 and 6 plates is unlucky so you can amuse your guests by serving 1 on an oddly matched plate.
