Yaki Onigiri (Japanese Soy-Glazed Grilled Rice Balls)

The rice grains are shaped into triangles or rounds while they remain warm and pliable, as the grains lose their natural binding ability once they cool and lose their moisture. During the shaping process, pressure must be applied with even distribution across the rice to prevent the grains from becoming a dense and compacted mass. This careful handling ensures that the interior of the rice ball maintains a soft texture with each individual grain remaining distinct after the grilling process is complete. The cooking method involves pan-grilling the rice balls using a small amount of sesame oil over a medium-low flame. This specific heat level is necessary to allow the starch on the surface of the rice to caramelize at a slow pace, resulting in a thin and crackling crust while the center of the onigiri remains moist. It is important to let the rice balls sit undisturbed in the pan for three to four minutes on each side before they are turned. This waiting period allows the outer layer to set properly and prevents the rice from tearing or sticking to the pan when it is time to flip them. A glaze made from a combination of soy sauce, mirin, and sugar is applied to the surface in several thin coats. Brushing the glaze on in multiple light passes, rather than applying a large amount of the liquid at the start, prevents the sugar content from burning or charring. This technique creates a deep savory flavor and a lacquered sheen on the exterior of the rice. The finished onigiri have a savory and slightly sweet profile, with edges that become chewy where the glaze has concentrated during the cooking process. A narrow strip of nori seaweed is often wrapped around the base of the rice ball to provide a salty element that balances the glazed exterior. When served with miso soup and pickled radish, these grilled rice balls function as a light meal.
