Grated fresh turmeric gives this grilled chicken a golden glow, while plenty of garlic, ginger, and puckery tamarind add bright flavor. Coconut charcoal burns exceptionally clean, letting the marinade shine. In Bali, Indonesia, Ibu Djelantik serves this chicken with her version of sambal matah, a bright, slaw-like condiment with chiles, shallots, and makrut lime or Key lime juice that offers a refreshing counterpoint to the chicken.
