Devil’s Onigiri Copycat Ingredients
For the Rice Balls
• Cooked Japanese Short-Grain Rice – This is the essential base with a chewy texture; freshly cooked yields the best flavor.
• Tempura Flakes (Tenkasu) – They create a delightful crunch; panko can be used in a pinch, but the taste will differ.
• Aonori (Dried Green Seaweed Powder) – Adds a burst of umami; if you can’t find it, finely shredded nori is a suitable substitute.
• Japanese Soy Sauce (Koikuchi Shoyu) – Essential for depth and saltiness; opt for tamari for a gluten-free version.
• Sugar – Balances the saltiness and enhances that addictive umami flavor; coconut sugar can be a great swap if desired.
• Dashi Granules – A key ingredient for that authentic umami taste; mushroom powder works as a vegetarian alternative.
• Toasted Sesame Oil – Brings a nutty richness; regular sesame oil can be used if you’re in a pinch.
• Chinese-Style Chicken Bouillon Powder – Adds a rich flavor boost; for a vegetarian option, use vegetable bouillon powder.
To Serve
• Optional Fillings – Experiment with fun choices like pickled plum, grilled salmon, or creamy avocado for a tasty surprise!
Step‑by‑Step Instructions for Devil’s Onigiri Copycat
Step 1: Prepare the Flavor Mixture
In a large mixing bowl, combine the tempura flakes, aonori, soy sauce, sugar, dashi granules, toasted sesame oil, and chicken bouillon powder. Use a wooden spoon to mix these ingredients thoroughly for about 1–2 minutes, until the liquid is mostly absorbed and the mixture is cohesive. You should see the flakes evenly coated in the flavorful blend, creating a tantalizing base for your Devil’s Onigiri.
Step 2: Mix in the Rice
Next, add the freshly cooked Japanese short-grain rice to the mixture. Using a spatula or your hands (with wet fingers to avoid sticking), gently fold the rice into the flavorful mixture until it’s evenly coated, about 2–3 minutes. Ensure that each grain of rice is infused with the savory flavors as you work, creating that irresistible taste reminiscent of Lawson’s famous onigiri.
Step 3: Portion the Rice Mixture
Once the rice is fully coated and the flavors have melded, divide the mixture into equal portions using a spoon or your hands. Aim for around 1/4 cup for each rice ball to achieve a consistent size. You should have about 6-8 portions total, giving you just the right number of Devil’s Onigiri to satisfy your cravings or for sharing with friends and family.
Step 4: Shape the Rice Balls
Using a rice ball mold (or your hands if you prefer), shape each portion into a firm rice ball, pressing gently to hold the form without crushing the rice. If using a mold, fill it with the rice mixture, then press down firmly and release to achieve a perfect shape. Each ball should feel compact and sturdy, showcasing a lovely glossy exterior from the tempura coating.
Step 5: Serve or Store
Once shaped, your Devil’s Onigiri are ready to be served! Enjoy them immediately, or for later consumption, wrap each rice ball in plastic wrap to keep them fresh. If you’re planning to take them on-the-go, consider using an ice pack to maintain their delicious flavor and texture. Whether as a quick snack or a delightful lunch, these onigiri are sure to impress!
