Pla Tod Yam Mamuang
This thai fried sea bass recipe deep-fries a whole sea bass until golden and crisp, then piles it with a green-mango salad of shallot, chilli, herbs and roasted cashews. One serving is about 326 g of fish and salad, excluding bones.
Pla tod yam mamuang is a Thai coastal favourite: a whole fish fried until the skin shatters, crowned with yam mamuang, a salad of sour green mango, shallot, chilli and herbs. Sea bass (pla kaphong) is the fish most often used in Thai restaurants, and the dish shows the Thai kitchen's signature balance — the sour mango and lime cut the richness of the fried fish, the fish sauce adds salt, the palm sugar adds sweetness, and the chilli adds heat. It is distinct from Thailand's steamed fish dishes, which use the same fish but a gentle lime-chilli broth instead of hot oil.
Pairs well with: Steamed jasmine rice and a cold Thai beer

A true pla tod yam mamuang is a whole fish fried until the skin is crisp enough to shatter, with the mango salad spooned on top at the last moment — never a fillet drowned in sauce, and never steamed.
Execution Methodology & Culinary Technique
Prep Stage: Score, Slice and Mix the Dressing
25 Mins • Fish Prep & Mango Salad
Score and dry the sea bass, dust it with rice flour and cornstarch, julienne the green mango, slice the shallot and chilli, and whisk the lime, fish sauce, palm sugar and garlic into a dressing. Keep the dressing separate from the mango until the fish is fried, so the salad stays crisp.
Maestro Tip: Dry the fish properly — water on the skin is the main reason fried fish spits oil and turns soggy instead of crisp.
10 Mins Room temperature, about 20°C (68°F)
Rinse the sea bass and pat very dry inside and out with kitchen paper. Score 3 diagonal cuts about 1 cm deep on each side so the heat reaches the thick flesh, rub with the salt, then dust all over with the rice flour and cornstarch, shaking off the excess. A thin, even coat is what crisps — a thick coat turns gummy.
Score through the skin but not into the bone; the cuts also help the coating grip.
Done when: The fish is dry to the touch with a thin, even white dusting and no wet patches.
10 Mins Room temperature, about 20°C (68°F)
Whisk the lime juice, fish sauce, palm sugar and garlic until the sugar dissolves. Toss the julienned green mango, shallot, chilli, coriander and mint with the dressing, then fold in the cashews. Taste — it should be sour first, then salty, then sweet, with heat behind it. Leave the salad to sit while the fish fries so the flavours wake up.
Dress the salad just before frying the fish, not hours ahead, or the mango softens and the cashews go soggy.
Done when: The mango is glossy with dressing, the cashews are still crunchy, and the salad tastes sour, salty and hot.
5 Mins Oil at 180°C (350°F)
Pour the oil into a deep wok or pot to a depth of about 5 cm and heat to 180°C (350°F). A cube of bread should turn golden in about 30 seconds. Keep a lid nearby and never leave hot oil unattended.
If you have no thermometer, a wooden chopstick dipped in the oil should fizz with steady small bubbles.
Done when: The oil shimmers and a test cube of bread browns in about 30 seconds.
10 Mins Oil at 180°C (350°F)
Lower one fish at a time into the oil, away from you, and fry 5–6 minutes per side without moving it — the skin needs stillness to crisp. Turn once with tongs and fry until the skin is deep golden and the flesh at the thickest part flakes easily and reaches 63°C (145°F). Lift out and drain on a rack, not on paper, so the underside stays crisp.
Do not crowd the wok — two fish at once drops the oil temperature and the skin steams instead of frying.
Done when: The skin is deep golden and crackles when tapped, and the flesh flakes and is opaque to the bone, 63°C (145°F).
5 Mins Serve hot — above 60°C (140°F)
Lay each fish on a platter, spoon the green-mango salad generously over the top, and serve immediately with steamed jasmine rice. The salad goes on at the table, never ahead, so the skin stays crisp under it.
Serve the extra salad in a bowl on the side — guests can add more as the fish is eaten.
Done when: The fish is steaming, the skin still crisp under the bright green mango salad.
Finishing Touches & Plating
Taste the mango salad before serving and adjust in tiny amounts — more lime if it needs brightness, a pinch more palm sugar if the mango is very sour. The fish must be eaten at once, while the skin is still crisp.

Food Pairings
To optimize nutrient absorption and elevate the sensory depth, pair with these authentic accompaniments:
Sides
Steamed Jasmine Rice
Plain jasmine rice soaks up the mango-salad dressing and balances the fried fish — the essential partner for a Thai fish dish.
Vegetables
Cucumber Salad
Cool sliced cucumber with a little vinegar gives a mild, crisp counterpoint to the chilli heat of the mango salad.
Drinks
Thai Iced Tea
Sweet, creamy iced tea tames the chilli heat and matches the sweet-sour notes of the mango dressing.
Sauces
Sweet Chilli Sauce
A small dish of sweet chilli sauce on the side lets each person add sweetness where the mango is at its sourest.
Complete menu
Serve the fried sea bass as the main dish with steamed jasmine rice, a cucumber salad and Thai iced tea, or as the centrepiece of a Thai family meal with a soup and a stir-fry.
Digestive Guardrails
To prevent digestive distress, sluggishness, or palate clash, avoid pairing the dish with these elements:
Dressing the Fish Too Early
Mango salad left sitting on the fish softens the crisp skin within minutes. Spoon it on at the table, just before eating. This is general information, not medical advice.
Reusing Frying Oil Many Times
Oil heated repeatedly to frying temperature breaks down and can form harmful compounds — strain and reuse it once at most, then discard it. This is general information, not medical advice.
Undercooking the Fish
Fish must reach 63°C (145°F) at the thickest part. A whole fish that looks done outside can still be raw near the bone — check it flakes cleanly. This is general information, not medical advice.
General information only, not medical advice — consult a doctor for personal dietary decisions.
