Instructions
- In a medium-sized bowl, combine tuna, Japanese mayo, soy sauce, rice vinegar, & sriracha (if using). Set aside.
- In the onigiri mold, sprinkle a very small amount of salt, add enough rice to cover the bottom of the mold. Then, add about 1 ½ tablespoon of tuna filling in the center, then more rice on top to cover the filling. Note that the amount of rice and filling depends on the size of the mold. For best results, make sure your rice & filling are really packed in.
- Put the top of the mold on top, then gently & firmly press to make rice tightly packed. You should feel a little resistance, but if you don’t, you might want to add a bit more rice so your onigiri is full & tightly pressed together. Press the back of the mold to release the onigiri.
- Wrap onigiri with a piece of nori.
- Roll the sides of the onigiri in furikake, if using. Repeat for remaining filling & rice. Enjoy immediately!
Notes
- Short Grain Rice: Sushi rice is used for this recipe, which has a stickier consistency compared to long grain rice. You can easily find it at local Asian & Japanese markets or online.
- Japanese Mayo: I HIGHLY recommend using Japanese mayo for this recipe! It's creamier with a subtle tang & there's no going back :) Find it at local Asian & Japanese markets or online & sometimes even at some local grocery stores in the Asian/International section.
- Soy Sauce: I'm using regular (not low-sodium) soy sauce for its saltiness & umami.
- Rice Vinegar: Just a touch of rice vinegar adds balance to the creaminess & saltiness from the mayo, soy sauce, & salt.
- Sriracha: This is totally optional! It's a great addition if you love spice, but again, adjust to your taste buds!
- Salt: A sprinkle of salt on the rice is traditionally used to season the rice as well as help preserve the onigiri. Keep in mind, a little goes a long way - you don’t want your onigiri too salty!
- Nori: This dried seaweed adds flavor & also helps prevent your fingers from sticking to the onigiri while eating.
- Furikake: There are a wide variety of furikake, so feel free to experiment/use your fave kind of furikake!
