A whole fish fried until the skin crackles, then drenched in a sweet-sour-spicy chile garlic sauce that pools into the flesh.
Pla rad prik is a staple of Thai seafood restaurants and home tables alike: a whole fish, usually snapper or sea bass, fried until the skin blisters and the flesh stays moist, then covered in a glossy sauce built from garlic, chiles, tamarind, palm sugar, and fish sauce. The sauce is what defines the dish -- it has to hit sour, sweet, salty, and spicy all at once, and it's poured on hot so it sizzles against the crisp skin. The technique hinges on getting the fish properly dry before frying (patted with paper towels, sometimes dusted lightly in rice flour) so the skin actually crisps rather than steams in the oil. A wok with at least 2 inches of oil, heated until a chopstick dropped in bubbles immediately, gives the best crackling texture. The sauce is built separately in a small pan while the fish rests, so both come together hot. Served whole on a platter with jasmine rice, this is a dish for the center of the table -- everyone picks at the crisp tail, the sauce-soaked flesh near the head, and mops up extra sauce with rice.
Serves 4
Score the fish 3 times on each side, diagonally through the thickest part. Pat completely dry with paper towels, then dust lightly with rice flour.
Heat oil in a wok over high heat until it reaches 180C/350F -- a piece of garlic should sizzle immediately on contact.
Carefully lower the fish into the oil. Fry 6-8 minutes per side until the skin is deep golden and crisp and the flesh flakes easily. Drain on a rack.
In a small pan, fry garlic and chiles in 1 tbsp of the frying oil for 30 seconds until fragrant. Add fish sauce, palm sugar, tamarind, and water, and simmer 2-3 minutes until glossy and slightly thickened.
Pour the hot sauce directly over the fried fish so it sizzles. Scatter with Thai basil and spring onions and serve immediately with jasmine rice.
Pat the fish bone-dry before frying -- any surface moisture causes violent oil splatter and a soggy skin.
Use a thermometer if you have one; oil under 170C makes the skin greasy instead of crisp.
Make the sauce while the fish drains so both are hot when they meet.
Pla rad prik with a whole fried fish substituted for pan-fried fillets if a whole fish isn't available.
Add sliced bell pepper and onion to the sauce for more body, common in restaurant versions.
Swap tamarind for extra lime juice if tamarind paste isn't on hand.
Best eaten fresh since the fried skin loses crispness quickly. Leftover fish and sauce can be refrigerated separately up to 2 days; reheat the fish in a hot oven, not a microwave, to partially recrisp the skin.
Pla rad prik (literally 'fish covered in chile') is a long-standing dish in Thai restaurant and home cooking, reflecting the central Thai balance of sour, sweet, salty, and spicy achieved through tamarind, palm sugar, fish sauce, and chile in a single sauce.
Yes -- pan-fry firm white fish fillets like snapper or tilapia until crisp on both sides, then pour the same sauce over them.
The most common cause is moisture -- make sure the fish is completely dry before it goes in the oil, and don't skip the light rice flour dusting.
Use fewer chiles or remove the seeds and ribs before slicing them; the sauce will still have plenty of sour-sweet flavor without much heat.
