RECIPE: Mentsuyu Onigiri (Rice Balls)
Hand-held onigiri (rice balls) are the ultimate quick meal or snack. Available in an infinite variety of flavors and fillings, onigiri are commonly eaten for breakfast, packed in bento box lunches, and enjoyed on picnics and hikes. They provide a burst of energy and sustenance without being overly rich, making them the perfect traveling food.
While the most popular version of onigiri consists of plain white rice wrapped around a filling, this recipe for mentsuyu onigiri stirs toppings and seasonings directly into rice to create one homogenous mixture. We use tenkasu (tempura bits) for crunch, aonori (seaweed flakes) or negi (green onion) for flavor, and mentsuyu and katsuoboshi (bonito flakes) for umami. The mentsuyu flavors the rice and turns it a light brown color.
Onigiri come in a variety of shapes, from triangular to round to cylindrical. For this recipe, triangular or round shapes work best. Feel free to use a mold if you have one handy, otherwise simply shape the onigiri using your hands. Spoon the prepared rice onto a sheet of cling film, then twist and mold it into your desired shape. Unwrap the cling film, remove the rice, and place a strip of nori (dried seaweed) on each rice ball. Alternatively, you can use a shiso leaf in place of nori.
Portable, filling, and endlessly customizable, onigiri are the quintessential on-the-go food in Japan. Try this recipe for mentsuyu onigiri to understand what makes onigiri so special!
