Substitutions and Variations
The wonderful thing about onigiri is that it's very forgiving, and you can add all kinds of variations.
- Soy sauce - if you're gluten-free, use gluten-free soy sauce or coconut aminos.
- Furikake - instead of (or in addition to), you can use Furikake to dip the onigiri in.
- Spicier tuna - you can add as much or as little sriracha as you'd like.
- Avocado - it's a nice creamy addition you can add when you add the tuna before topping it with additional rice.
- Dipping sauce - if you don't want the dipping sauce, you can omit it, but I think it's a nice addition. You can always just use soy sauce as your dip.
If you're paleo, you can find a spicy tuna sushi bowl recipe on the blog, which is delicious and friendly for those who can't have rice.
Storage
The onigiri can be stored in the refrigerator for two days. You can also make the rice in advance, and assemble it when you're ready.
Top Tip
Make sure you're using sushi rice as it's sticky. Other types of rice will not work as they are not starchy enough.

FAQ
Whenever you make onigiri, you want to use short-grain rice that is used for making sushi.
Sushi rice is typically a short-grain rice that is sticky, gelatinous, and much starchier than this one. Additionally, sushi rice is mixed with vinegar, salt, and sugar to give it extra flavor.
No, nori is specifically used for making sushi, while nori is very crispy and not pliable at all.
Sushi rice is extremely sticky so in order to be able to form the onigiri, you want to to have moist hands to properly work and shape the rice.
Japanese mayo is a great if you can tolerate MSG. I cannot so I don't generally use it. You may be able to find some brands without it.
