Cooked the rice according to instructions.
Let it cool slightly then combine with rice vinegar and sesame oil.
Dice the sashimi salmon finely and combine in a bowl together with ponzu, rice vinegar, sesame oil, fresh grated ginger and lime juice.
Assembly the tartare by placing half or all of the rice at the bottom of a plate using a round mold, making sure it gets a circulare form and stays in place. Gently press the rice down to make sure it sits. Place the rest of the rice in a seperate mold on a seperate plate.
Next divide the avocado between the two molds, pressing down gently, followed by the salmon.
Top with thinly sliced radish, wakame salad and sesame seeds.
