A whole fish deep-fried until crisp throughout, served with a sweet-sour-hot sauce of tamarind water, palm sugar, fish sauce, dried chillies, and fried garlic — the 'three flavours' of the name referring to the sauce's combined sweet, sour, and salty character. Pla sam rod demonstrates one of the Thai kitchen's most satisfying contrasts: the fish's crisp, dried exterior against the sauce's glossy, sweet-sour flood of flavour.
**The fish:** - Deep-fried whole at 180°C until completely crisp throughout — this requires approximately 8 minutes per side for a 500g fish. The fish is done when the skin is mahogany-coloured and completely rigid — no give anywhere on the fish. The completely crisp preparation is a 'dried' fish — it has lost most of its moisture to the oil, its flesh is firm rather than yielding, and it holds against the sauce's flood without softening immediately. **The sauce:** 1. Fry garlic (5 cloves, sliced) in 3 tablespoons oil until golden. Set aside. 2. In the same oil: add bird's eye chillies (5, sliced). Fry briefly. 3. Add tamarind water (4 tablespoons), palm sugar (3 tablespoons), fish sauce (2 tablespoons). 4. Cook over high heat until the sauce reduces and thickens — a syrup-like consistency. 5. Add the fried garlic. 6. Pour over the fish immediately before service. Decisive moment: The complete crisping of the fish's exterior. A fish that is 'almost crisp' will absorb the sauce and become soft within 60 seconds of service. A completely crisp fish remains firm for 3–4 minutes after the sauce is applied — long enough for service and eating. Judge by touch: the fish should feel rigid throughout, like crackling.
