1In a bowl, combine calamansi juice, vinegar, soy sauce, annatto oil, garlic, ginger, brown sugar, salt, and pepper to make the marinade.
2Marinate the chicken thighs in the mixture for at least 2 hours, or preferably overnight for maximum flavor.
3Preheat the grill. Grill the marinated chicken, basting with the marinade and turning occasionally until cooked through and charred on the edges.
4Serve hot with steamed rice and a side of sinamak (spiced vinegar) for a truly authentic Bacolod dining experience.
Don't be tamad to marinate the chicken for long to achieve that legit flavor. Make sure your grill is init enough to get that smoky goodness. If you want to level up, pair it with a cold glass of calamansi juice with mint leaves for that extra fresh kick!
