Ingredients
- 1 whole sea bass or snapper (about 1.5 lb), cleaned and scaled
- 1/2 cup cornstarch
- Oil, for deep-frying
- 3 cloves garlic, minced
- 2 red chilies, finely chopped
- 1 tablespoon fish sauce
- 2 tablespoons sugar
- 1 tablespoon tamarind paste
- 1/4 cup water
- 1 cup Thai basil leaves
- 1 red bell pepper, thinly sliced
- Lime wedges, to serve
- Steamed jasmine rice, to serve
Instructions
- Score the fish deeply on both sides with diagonal cuts. Pat very dry with paper towels and dust evenly with cornstarch.
- Heat 2 inches of oil in a large wok to 375°F (190°C). Fry the fish for 6 to 7 minutes per side until deep golden and crisp. Drain on a wire rack.
- Heat 1 tablespoon of oil in a small pan. Cook the garlic and chilies for 1 minute until fragrant.
- Add the fish sauce, sugar, tamarind paste, and water. Simmer for 3 minutes until the sauce thickens into a syrupy glaze.
- Stir in the bell pepper and half the basil leaves and cook for 1 minute.
- Place the crispy fish on a serving platter and pour the hot chili sauce over the top.
- Scatter the remaining basil over the fish and serve immediately with lime wedges and jasmine rice.
Pro tips
- Dry the fish thoroughly before dusting — wet skin and hot oil do not mix.
- The oil must be hot enough that the fish sizzles on contact, or it will turn greasy.
- Pour the sauce over the fish only at serving time so the skin stays crisp.
- Score deeply so the fish cooks evenly and the sauce seeps into the flesh.
Frequently asked questions
What fish is best for pla rad prik?
Sea bass, snapper, or tilapia all work well. Choose a whole fish with firm flesh that crisps beautifully when fried.
Can I use fish fillets instead of a whole fish?
Yes — use thick fillets and fry for 3 to 4 minutes per side. The presentation is simpler, but the flavor is the same.
Is pla rad prik very spicy?
It has a warm, sweet heat from the chilies, balanced by sugar and tamarind. Reduce the chilies to one for a milder version.
What is tamarind paste?
A sour, fruity paste made from tamarind fruit. It gives the sauce its signature tang — lime juice is the best substitute.
