If you prefer a little heat in your grilled meat, try making Spicy Yakiniku. This recipe adds a kick of spice to the classic dish by incorporating chili paste or hot sauce into the marinade. The ingredients and steps for this recipe are similar to the Classic Yakiniku, but with the addition of the spicy element. The marinade is made by combining soy sauce, mirin, sake, sugar, garlic, ginger, and chili paste or hot sauce. The meat and vegetables are then marinated in this spicy sauce and grilled to perfection. The result is a tantalizing combination of flavors, with the heat from the chili paste complementing the smoky grilled meat. Serve the Spicy Yakiniku with a side of steamed rice and a cooling cucumber salad to balance out the spiciness.
