Step‑by‑Step Instructions for DEVIL ONIGIRI
Step 1: Combine Ingredients
Begin by gathering all your ingredients—about 300g of cooked rice, 2-3 tablespoons of Tenkasu, ½ tablespoon of aonori, 1 tablespoon of mentsuyu, and sesame seeds. In a mixing bowl, add the warm cooked rice and sprinkle in the sesame seeds, Tenkasu, aonori, and mentsuyu. This mixture should feel slightly sticky and have a balanced, savory aroma, indicating it’s ready for the next step.
Step 2: Mix Thoroughly
Using a spatula or your hands, gently combine the ingredients. Be careful not to break the rice grains; a light hand will ensure the mixture retains its texture. Mix until all components are evenly distributed, about 2-3 minutes. The rice should hold its shape yet remain slightly warm, giving you a better consistency for shaping the onigiri.
Step 3: Shape the Onigiri
Now it’s time to shape your DEVIL ONIGIRI! Wet your hands slightly to prevent sticking, then scoop a generous amount of the rice mixture. Form it into a triangle about 3 inches wide, pressing gently to compact the rice while maintaining a fluffy texture. Repeat this process until all the mixture is shaped. You’ll love how each onigiri becomes a delightful little package!
Step 4: Heat a Pan
In a frying pan, heat a drizzle of oil over medium heat until it shimmers, about 3-4 minutes. This temperature is ideal for achieving that crispy exterior. Carefully place your shaped onigiri in the hot pan, avoiding overcrowding, and allow them to cook undisturbed for 3-4 minutes until they develop a golden crust.
Step 5: Flip and Crisp
Once the underside is golden, gently flip each DEVIL ONIGIRI using a spatula. Let them cook for an additional 3-4 minutes on the other side. Keep an eye on them to ensure an even crisp without burning. A lovely golden-brown color is your cue that they are perfectly toasted and ready to be removed from the heat.
Step 6: Serve or Store
Transfer your beautifully toasted DEVIL ONIGIRI onto a paper towel-lined plate to absorb any excess oil. Serve them warm, perhaps with some dipping sauce or alongside Japanese pickles, to elevate your snacking experience. If you’re saving some for later, let them cool completely before storing them in an airtight container; they’ll retain their lovely texture for a later delicious treat!

Expert Tips for Devil Onigiri
-
Use Warm Rice: Always start with slightly warm rice for easier shaping; cold rice can crumble and won’t hold your shape well.
-
Gentle Mixing: Mix ingredients gently to preserve the structure of the rice grains; over-mixing makes them mushy and less appealing.
-
Watch Salt Levels: Be cautious with mentsuyu; its saltiness can vary greatly. Start small and adjust to your taste for the perfect flavor balance.
-
Crispy Finish: For an extra crunch, let the onigiri rest for a minute in the pan after flipping—this ensures a golden, crispy exterior on both sides.
-
Customizable Ingredients: Feel free to swap Tenkasu with crushed tempura flakes or add a sprinkle of chili flakes for a spicy kick.

Devil Onigiri Recipe FAQs
What kind of rice is best for Devil Onigiri?
I recommend using short-grain Japanese rice, as it has the perfect stickiness and texture to hold the onigiri together. Long-grain rice won’t provide the same consistency.
How should I store leftovers of Devil Onigiri?
For the best flavor, consume your Devil Onigiri fresh! If you have leftovers, place them in an airtight container in the fridge for up to 3 days. It’s best to let them come to room temperature before munching, or you can lightly reheat them to restore some crispiness.
Can I freeze Devil Onigiri?
Absolutely! To freeze, shape the uncooked onigiri and wrap each piece tightly in plastic wrap. Place them in a freezer-safe bag or container, and they should be good for up to 1 month. When you’re ready to enjoy, you can pan-fry or bake them from frozen for about 5-8 minutes until crispy and warmed through.
What do I do if my onigiri fall apart?
If your Devil Onigiri falls apart, it’s often due to using cold rice or over-mixing the ingredients. Make sure your rice is slightly warm when mixing and use a gentle hand when combining. If it continues to crumble, try adjusting the amount of mentsuyu as it affects the moisture level.
Are there any allergens I should be aware of in Devil Onigiri?
Indeed, mentsuyu often contains soy sauce, which is a common allergen. If you’re cooking for someone with soy allergies, look for gluten-free mentsuyu or create your own alternative with dashi, mirin, and sugar. Always check labels if you’re unsure about any ingredient.
Can I customize the filling for Devil Onigiri?
The more the merrier! You can definitely personalize your onigiri by adding ingredients like cooked vegetables, meat, or even spicy seasonings to the rice mixture. Just keep in mind that adding too much moisture may affect the shaping.
