Chicken inasal is a popular Filipino grilled chicken dish known for its distinct, flavorful marinade. The chicken is marinated in a mixture of calamansi (or lemon), soy sauce, vinegar, garlic, ginger, and annatto oil, giving it a vibrant orange color and a tangy, slightly sweet taste. It is then grilled over charcoal, imparting a smoky flavor and achieving a crispy, caramelized exterior while keeping the meat tender and juicy.
