To achieve the perfect yakiniku, it's important to master the art of grilling. The traditional method is to use a charcoal grill, which imparts a smoky flavor to the meat. However, if you don't have a charcoal grill, a gas grill or even a stovetop grill pan can work just as well. Preheat the grill to medium-high heat and lightly oil the grates to prevent sticking. When grilling the meat, make sure to cook it quickly over high heat to seal in the juices and create a nice charred crust. It's best to grill the meat in small batches to avoid overcrowding the grill and ensure even cooking. As for the vegetables, they can be grilled until they are slightly charred and tender. Remember to brush the yakiniku sauce onto the meat and vegetables while grilling to enhance the flavor.
