Step 1

Make the filling: For the tuna mayo filling, add the canned tuna and Japanese mayonnaise to a small bowl and mix well. Season with salt and pepper to taste.

Step 2

Season the rice: Saute the finely diced carrots with a bit of oil until soft, about 3 minutes. Add the carrots and toasted sesame oil to the warm rice and mix together.

Step 3

Add filling and shape rice balls: Take 2 tablespoons of rice and gently flatten it against your hand. Add about 1 tablespoon of filling to the center and top it with a bit of rice. Gently but firmly shape the rice into a ball while encasing the filling. Tip: Apply a bit of vegetable oil to food-safe gloves for easy handling.

Step 4

Seaweed seasoning: Roll each rice ball in seaweed seasoning. Serve and enjoy!
