Fresh or smoked oysters can be used.
- Cook the rice in the water according to the packet instructions. Add a little more water if necessary. Cover and stand for 5 minutes then fluff with a fork adding the sushi su at the same time.
- Meanwhile, combine the mayo and wasabi.
- Place the salmon in a microwave dish and sprinkle with the lemon juice. Cover and microwave on high power for 1½ - 2 minutes, until just cooked. Remove the skin and divide the salmon into 4 pieces.
- Take a mould or biscuit cutter and make 4 round discs of the rice to serve as bases. Top with the cucumber, salmon and oysters, wasabi mayo, coriander leaves and another smaller round disc of rice. Can be garnished with strips of fried nori or cavolo nero leaves.
