Chicken pieces marinated in fish sauce, garlic, coriander root, white pepper, and palm sugar — then deep-fried until deeply golden, the skin crisp and the interior juicy. Thai fried chicken (gai tod) diverges from both Western fried chicken and Korean fried chicken in its absence of a thick batter — the marinade dries to a thin, adherent coating on the chicken surface that crisps directly against the oil, producing a preparation that is less about the coating and more about the Maillard-developed marinade on the chicken's own skin. The coriander root-garlic marinade is the dish's aromatic signature.
**The marinade:** - Coriander root: pounded with garlic to a smooth paste (same as gai yang marinade, Entry TH-26). - Fish sauce: the primary salt and the source of the inosinic acid that caramelises against the chicken skin during frying. - White pepper. - Palm sugar: a small amount — for caramelisation. Marinate 2–4 hours minimum. **The frying:** - Cut into pieces: drumsticks, thighs, and wings. These pieces cook to their correct internal temperature in the time the skin needs to achieve the correct crust. - Fry at 170°C for 12–15 minutes for thighs. - No batter, no flour coating — the marinade dries on the chicken surface during the frying and becomes the crust. **The two-temperature technique (optional but preferred):** 1. Fry at 160°C for 10 minutes — the interior cooks through without the marinade burning. 2. Increase oil to 180°C. Return the chicken for 2–3 minutes — the higher temperature crisps the surface without further cooking the interior. 3. This technique produces a crispier result than a single-temperature fry. Decisive moment: The skin colour — deep amber-gold, not golden-pale. The Maillard products of the fish sauce and palm sugar in the marinade provide deeper colour than a plain salt marinade would — the correct endpoint is deeper than the golden-pale of Western fried chicken.
