Instructions

  • Sprinkle the onigiri mold with salt and place about 50-60g of rice inside. Make a dent in the middle and add about 2 tsp of tuna mayo filling. (If shaping by hand, wet your hands with cold water and sprinkle with salt. Take 100-120g of rice and press it flat before placing the filling in the middle.)

Notes

Best eaten the same day. Wrap and pack in a bento with an ice pack to keep it cool. I recommend storing the nori separately and wrapping right before eating.
Add wasabi, shichimi or chili sauce to the tuna mayo for a spicy kick.
To store, wrap each onigiri with plastic wrap (without nori) and store in the freezer. Defrost in the microwave and wrap with nori just before eating.
