cook the rice

Step 1

Cook The Rice

Wash rice under cold running water and drain several times until the water runs clear.
 Drain the rice and put into a pan with a tight fitting lid and 350ml of cold water.
 Bring to the boil with the lid on.
 Turn the heat down as low as it'll go and simmer for 10 minutes then remove from the heat and leave to stand for 15 minutes. Do not remove the lid throughout as the trapped steam is what best cooks the rice but do occasional shake the pan.

season the rice

Step 2

Season The Rice

Dissolve the salt and sugar into the vinegar and mirin and stir through the rice after the 15 minutes. Transfer the cooked rice to a bowl and allow to cool.

Step 6

Prepare The Tuna

Chop the tuna steaks into very fine cubes using an incredibly sharp knife. Wash and slice the spring onions adding them to the chopped tuna in a bowl. Mix the mayonnaise with the wasabi and add to the tuna mixture to bind, along with salt to taste. Press the tuna mixture into 6 patties, the same size as your rice patties, and leave in the fridge to rest.

Deep Fry The Burgers

Mold the cooled rice into 12 discs approximately 5cm across and 2cm thick making sure it’s well compact, use damp hands to do this. Lower the shaped rice into the hot oil to fry for 2 minutes to go golden and crispy on the outside. Scoop out and drain on kitchen paper to get rid of excess oil.
