Gai Yang (Thai Grilled Chicken)

Gai yang (ย่างไก่ — grilled/roasted chicken) is a Thai street food staple most associated with northeastern Isan cookery — where it is served with sticky rice and som tum as the definitive Isan meal. Thompson's *Thai Street Food* treats gai yang as one of the defining street preparations, emphasising the charcoal component as essential.

Thai grilled chicken — marinated in coriander root, garlic, lemongrass, and fish sauce, then cooked over charcoal at medium heat with patience and constant turning until the skin is lacquered dark-golden, the interior is completely cooked through, and the rendered chicken fat has basted the surface into a state of fragrant, slightly charred perfection. Gai yang is the most satisfying application of the Thai grill and a preparation that rewards the cook who gives it time and resists the impulse to rush.

Charcoal-grilled chicken with a coriander root and lemongrass marinade achieves its flavour through three simultaneous processes: the Maillard browning of the surface proteins and sugars, the caramelisation of the palm sugar and fish sauce marinade compounds, and the smoke-aromatic contribution of the charcoal. As Segnit notes, smoke and chicken is one of the most universally appealing flavour combinations — pyrolysis compounds from wood smoke are from the same Maillard-adjacent aromatic family as the browned chicken surface compounds, producing a unified character where smoke and Maillard are perceived as a single flavour rather than a combination.
