Method
- Score the fish three times on each side, slashing through to the bone. Pat very dry — wet fish steams in oil instead of frying. Dust lightly with rice flour, including inside the slashes.
- Heat oil in a wok or wide pot to 180°C — deep enough to half-submerge the fish. A wooden chopstick should bubble vigorously when dipped. Lower the fish in carefully, head first.
- Fry seven to nine minutes per side, basting the top with hot oil with a ladle. The skin should be deeply golden, almost mahogany at the edges, and the flesh nearest the bone should flake easily. Lift onto a rack.
- In a clean pan with 2 tbsp of the frying oil, sauté garlic and shallots over medium until pale gold. Add chilies and stir thirty seconds.
- Whisk tamarind, palm sugar, fish sauce, soy sauce, and water in a bowl, then pour into the pan. Bubble three to four minutes until the sauce is thick enough to coat the back of a spoon. Taste — sour, sweet, salty, with chili heat building.
- Place the fish on a long platter. Pour the sauce over so it pools around but lets the crispy fins poke through. Scatter cilantro and serve immediately with steamed rice — the sauce is the whole point.

Cultural Note
Pla rad prik is centerpiece food — birthdays, Lunar New Year, the moment a household decides the meal is special. Buying a whole live fish at the market and frying it yourself is the move; restaurant versions can be timid with the chili. The fish's eye is a delicacy reserved for the eldest at the table in many Thai-Chinese families. The sauce-to-rice combination is so good that a second plate of rice is always quietly produced.
