Instructions
The Preparation
- Gather the ingredients. Start by washing the 1 cup short-grain rice in cold water to remove the starch then cook it in the rice cooker. The rice should be done by the time you are finished with the spicy tuna mix.
The Spicy Tuna
- To make the spicy tuna salad, drain the can of 142 g Ahi tuna in olive oil then transfer to a bowl and break up the tuna chunks into small flakes using a fork. Add 2 Tbsp. Japanese Kewpie mayonnaise, 2 Tbsp. Sriracha and ½ tsp. soy sauce. Mix well to combine. If you do like too spicy, decrease the Sriracha.
- Add the chopped 3 green onion, ½ tsp. lemon juice and 2 Tbsp. roasted black sesame seeds mix well.
The Onigiri
- Prepare the onigiri rice by mixing 1 Tbsp. roasted black sesame seeds into the slightly cooled rice. Then cut the 2 Nori sheets into 3 pieces each.
- Wet the onigiri mold* with hot water and fill with rice, adding enough of tuna mayo filling to the center before topping with more rice and compressing firmly. Release the formed rice ball onto a plate or cutting board. Wrap each onigiri with a strip of nori, tuck the nori under the bottom. Place a spoon of tuna mayo filling on the top.*If no onigiri mold, use plastic wrap to help you shape it. I recommend watching a onigiri wrapping video if you are more visual.
The Serving
- Serve immediately for crispy texture. They should be eaten during the same day as the rice will harden if left in the fridge.
