Selected high-quality chicken is prepared using a steam-roasting process that locks in its original flavor, retains its tenderness, and imparts a unique charred aroma through roasting. It is infused with rich miso sauce, where the savory and slightly sweet flavors penetrate layer by layer, leaving each piece of chicken coated in the sauce. After steam-roasting, it undergoes sterilization, allowing for ready-to-eat consumption right out of the bag with no need for secondary cooking. The meat is tender and well-infused with flavor, and the miso aroma lingers, making it a convenient and delicious cooked food option.
