Chu Chee Pla (ฉู่ฉี่ปลา)

The Curry That Clings

ฉู่ฉี่ (chu chee) is not a coconut milk curry but a coconut cream curry — the thickest, glossiest sauce in the Thai repertoire, cooked down until it sits on the fish like custard rather than soup. Where other curries flood the plate, chu chee coats: every source here ends the dish the same way, with finely sliced kaffir lime leaves (ใบมะกรูดซอย) and sliced red chilli scattered over the top so the aroma hits before the first spoonful.

The method is what makes it. The cook fries the curry paste in coconut cream until the cream splits — the oil beads out and the paste turns deep red and glossy. Thai cooks call this หัวกะทิแตกมัน, and it is the same patient step that builds kaeng kua; skip it and the sauce stays pale and flat. Kapook's mackerel pot even adds water at this point and waits for the second split before the fish goes in.

The fish itself is negotiable in a way the cream is not. The classic restaurant chu chee is a fried fish — sea bass (ปลากะพง) or red tilapia (ปลาทับทิม) — with the sauce poured over, as in both Wongnai pots. But the curry is an old river-fish dish at heart, and Kapook's sheatfish recipe, taken from a Pantip cook, still makes it the traditional way: a fresh-pounded chilli paste, no coconut milk at all, the fish poached gently in the pan.

The Recipe (fried-fish classic, from Wongnai / Cookpad)

The poached pot (Kapook): 3–4 fresh mackerel, a third of a cup of ready-made red curry paste, 250 ml coconut milk, salt, sugar and soy or fish sauce — the fish poached in the curry and turned once, no frying. The whole-fish pot (Wongnai's red tilapia): a 1 kg fish deep-fried whole, the paste fried in plain oil with garlic and fingerroot, loosened with coconut milk and seasoned with oyster sauce, sugar and fish sauce. The river pot (Pantip via Kapook): sheatfish poached in a fresh-pounded paste of chillies, galangal, lemongrass and shrimp paste — no coconut milk anywhere — finished with sliced lemongrass.

The Method

1. The fish. Deep-fry the fish in hot oil until golden and crisp, then lift out and drain. Wongnai's tilapia cook salts the pan bottom so the skin never sticks, and fries bone-side first for a clean skin. Cookpad has the useful middle path: dust the fish with cornflour and fry only halfway if you mean to finish it in the sauce — and whatever you do, do not keep turning it, or the flesh breaks up.
2. The split. Heat half the thick coconut cream in a wok until it boils and the oil beads out on the surface — หัวกะทิแตกมัน. This is the step that decides the dish. Fry the chu chee paste in the split cream until it darkens and turns glossy; Cookpad works half a teaspoon of shrimp paste into the curry paste first for depth.
3. The sauce. Loosen with the remaining coconut cream, then season with fish sauce and palm sugar. Go easy on the sugar — chu chee is rich, not sweet — and remember most shop-bought paste is already salty.
4. The finish. Pour the sauce over the drained fish, or return the pieces to the pan for a minute to cook through. Scatter the sliced kaffir lime leaves and red chilli over the top, and spoon a little raw coconut cream over the sauce for the two-tone look Wongnai's sea bass pot is known for. Serve at once with hot jasmine rice — the sauce is the point, so do not skimp on it.

Where Thai Sources Disagree

How Western Versions Get It Wrong

• Making it a soup. Chu chee is a clinging cream sauce, not a broth. If the fish is swimming, the coconut cream has been swapped for coconut milk and the dish has lost its defining richness.
• Skipping the split. Dumping the paste into unheated cream and boiling produces a pale, grainy sauce. The หัวกะทิแตกมัน step — waiting for the oil to bead out of the cream — is what deepens the colour and the flavour; every Thai source treats it as the heart of the dish.
• Leaving out the kaffir lime leaves. The sliced kaffir lime leaves are not decoration — they are the aroma the dish is known for. Substituting lime zest changes the flavour; find the real leaves, fresh or frozen.
• Over-sweetening. Western "red curry" instincts add sugar until the sauce is dessert. Chu chee is rich from the cream and needs only a spoon of palm sugar to round it off.
• Any old white fish. Thai sources choose fish that hold together — sea bass, tilapia, mackerel, sheatfish. A flaky, soft fillet disintegrates in the cream and leaves you with fish porridge.

UK Ingredient Notes

• Chu chee paste (พริกแกงฉู่ฉี่): jars at Thai grocers and online Thai supermarkets — Mae Ploy and Lobo both make one. If you can only find red curry paste, Cookpad's fix applies: work half a teaspoon of shrimp paste (กะปิ) into it and it behaves like chu chee paste.
• Coconut cream: use the thick top of a full-fat tin, or buy pure coconut cream blocks. The dish lives or dies on the cream, so skip the "light" versions.
• Fish: sea bass or bream from any UK fishmonger or supermarket counter, fillets or one whole fish; firm white fish like pollock works if you handle it gently.
• Kaffir lime leaves (ใบมะกรูด): fresh at Thai grocers in season, frozen year-round — both slice beautifully once thawed.
• Red spur chillies (พริกแดง): long red chillies from the supermarket are the closest match for colour and mild heat; use fewer bird's eye chillies if you want it hotter.
• Palm sugar (น้ำตาลปี๊บ): soft brown sugar stands in without changing the dish much.
