Pla Rad Prik (Fried Fish with Chilli Sauce)
Why this recipe works
- Crisp fish, glossy sauce: Drying and lightly flouring the fish helps it fry to a crisp finish, while adding the sauce just before serving preserves the texture.
- Sweet-sour balance: Tamarind, lime, palm sugar and fish sauce create the sharp, sweet and savoury balance that defines the dish.
- Big Thai flavours: Garlic, shallot and fried dried chillies give the sauce aromatic depth, heat and a distinctive savoury edge.
Get the most out of this recipe
Adjust the heat
- For less heat: Shake out more of the chilli seeds before frying, or use fewer fried chillies as the final garnish.
- For more heat: Leave more seeds in the dried chillies, or scatter extra fried chilli over the fish just before serving.
- Keep the heat balanced: If the sauce tastes too sharp or fiery, adjust with a little more sweetness or fish sauce rather than diluting it heavily.
Texture tips
- Dry the fish well: Moisture on the skin stops the coating from frying cleanly, so pat the fish thoroughly dry before flouring.
- Sauce at the last moment: Spoon the chilli sauce over the fish only when ready to serve so the coating stays crisp underneath.
- Shake off excess flour: A light, even coating fries more cleanly than a thick layer, which can turn heavy or patchy.
Ingredient notes
- Choosing the fish: Sea bass works well because it has firm flesh and delicate flavour; sea bream is a good alternative with a similar texture.
- Tamarind brings the sourness: Tamarind paste gives the sauce its rounded, fruity tang, which is different from lime juice alone.
- Palm sugar flavour: Palm sugar adds a caramel-like sweetness that rounds out the fish sauce and tamarind.
Make-ahead tips
- Store fish and sauce separately: Keeping the sauce separate helps protect the fish coating from becoming soft in the fridge.
- Reheat for best texture: Warm the sauce gently with a splash of water, and reheat the fish in a 200°C (390°F) oven until piping hot.
- Best served fresh: The dish is at its crispest immediately after frying, especially once the sauce has been added.

Ingredients
Instructions
- Pat the sea bass dry, then make 3 shallow diagonal slashes on each side. Put the plain flour in a bowl and lightly coat the fish all over, shaking off any excess.
- Thinly slice the shallots and finely chop the garlic. Snip the dried red chilli into short pieces and shake out most of the seeds for a cleaner heat.
- Heat the vegetable oil in a wok or large frying pan over medium-high heat until a small pinch of flour sizzles immediately. Fry the dried red chilli for 20 to 30 seconds until darker and crisp, then lift out with tongs and set aside.
- Carefully lower the fish into the hot oil and fry for 6 to 8 minutes, turning once, until deep golden and the flesh flakes easily. Lift out and drain briefly, then place on a serving plate.
- Carefully pour off most of the oil, leaving about 2 tbsp in the wok. Add the shallots and cook over medium heat for 2 to 3 minutes until softened, then add the garlic and cook for 30 to 60 seconds until fragrant.
- Whisk the tamarind paste, fish sauce, palm sugar and water together, then pour into the wok. Simmer for 3 to 5 minutes, stirring, until glossy and lightly thickened.
- Squeeze in the lime juice, then taste and adjust with a little more lime if you want it sharper. Spoon the hot sauce over the fish and scatter over the fried chillies just before serving.
Recipe notes
Tips
- For the best crunch, make sure the fish is very dry before flouring, and keep the oil hot enough that the coating sizzles immediately.
- If you prefer a smoother sauce, whisk the tamarind paste with the water until fully dissolved before adding it to the pan.
- Take care with hot oil, and avoid this dish for vulnerable groups if you cannot be confident the fish is cooked through; it should flake easily and be opaque at the thickest part.
Substitutions
- Replace sea bass with sea bream for a similar texture and flavour.
- Replace palm sugar with honey for a slightly different sweetness.
- Replace plain flour with rice flour for a lighter, crisper coating.
Storage
- Refrigerate up to 2 days
- Store the fish and sauce separately in airtight containers. Reheat the sauce gently in a saucepan with a splash of water, and reheat the fish in a 200°C (390°F) oven until piping hot; add the fried chillies at the end to keep them crisp.
