Step 1

Combine tuna, hot sauce, mayonnaise, salt and pepper, green onion, lemon juice and pepper flakes into a bowl and mix thoroughly. Adjust seasonings to taste.

Step 2

Place into the refrigerator until ready to use, at least 1 hour. (The longer it sits, the more flavourful the tuna will be).

Step 3

When ready to assemble, using an onigiri mold, add about 1 heaping Tbsp of warm rice to the mold, press down lightly with a spoon.

Step 4

Add 1 Tbsp of spicy tuna filling over top of the rice.

Step 5

Finish by adding another 1 Tbsp of rice on top of the filling to encase it. Press the mold firmly to retain the shape of the rice ball.

Step 6

Open the mold and remove the onigiri.

Step 7

Dip the exterior of the onigiri into some sesame seeds and furikake if you wish, and wrap it with a piece of nori.
