To Make Temari Sushi
On a clean working bench, lay a sheet of plastic wrap and place the topping ingredient at the center. Dap a little wasabi on the sashimi, then place a rice ball on top.
Wrap the plastic firmly to form a ball shape. Repeat for the remaining toppings and rice balls.
Garnish the temari sushi with edible flowers or other seasonings to add more depth to the flavours. Serve with wasabi and soy sauce.
