Laab Pla Duk (ลาบปลาดุก)

The Larb That Swims In The Paddy

ลาบ (laab) is the Isaan minced-meat salad — any meat, pounded or minced, dressed with roasted chilli, toasted rice, lime and fish sauce, and ปลาดุก (pla duk) is the walking catfish that lives in every rice paddy and ditch in the region. Swap the usual pork for catfish and you get laab pla duk: the version the Institute of Nutrition at Mahidol University calls a signature of Isaan's merit-making feasts — catfish is cheap, everywhere, and its flesh is sweet, firm and rich, with no scales and few bones to fight.

Every published Thai recipe agrees on the start: the catfish is grilled first — over charcoal, about fifteen minutes, until the skin chars — and only then flaked and dressed. That grilling is the dish's whole flavour; the smoke is what you taste before the chilli arrives. The older village tradition — raw minced fish, its own bile for bitterness, a splash of fermented fish sauce — still exists, but no source we found minces the fish raw; they all send it through the fire.

What happens after the grill is where the recipes split. The quick home version dresses the warm flaked fish in a bowl and is done. The street version — ครัวคุณต๋อย's TV recipe — stir-fries the fish with garlic and young galangal until it turns golden and fluffy first. Krua.co's, from the แสงแดด cookbook house, warms the fish through gently with pounded old galangal and a spoon of water. Three routes to the same plate of sour-salty-hot fish with the nutty crunch of toasted rice on top.

The Recipe (home version, from Wongnai / Aroifin)

The warm pot (Krua.co): one catfish flaked coarse, warmed in a pot over medium heat with pounded old galangal and a little water (รวน), then 8 sliced shallots, 1½ tbsp fish sauce, 2 tbsp lime juice, toasted-and-ground dried bird's eye chilli, sliced fresh chillies, 2 tbsp toasted rice, spring onion, coriander and a crown of mint. The street pot (ครัวคุณต๋อย): five fish, minced; garlic and young galangal fried in a little oil until fragrant, the fish stirred through the pan until golden and fluffy (คั่วให้เหลืองฟู), then shallots, fried shallots, three kinds of coriander, kaffir lime leaves, mint, fried dried chillies, lime and fish sauce. The village pot (Mahidol): 234 g catfish with 30 g pla ra boiled with lemongrass and 235 g water — the fish chopped bones and all in a mortar with the boiled pla ra, lime, chilli powder and toasted rice. The weeknight pot (Kapook): one catfish pounded with young galangal, dressed light, under a pile of raw vegetables. The dry-or-wet pot (Esan108): two catfish minced with galangal — stir the mince dry in a pot if you want it crumbly, or dress it wet, as you like.

The Method

1. The fire. Grill the catfish over charcoal on a medium fire — Mahidol says about fifteen minutes, until the skin chars and the flesh cooks through. This step is the flavour: the smoke sits in the fish long after the dressing goes on.
2. The flake. Let the fish rest until just warm — Aroifin warns that flaking it scorching hot makes the meat mushy and watery. Strip the flesh from the head and burnt skin, pick out the larger bones, then mince fine. Wongnai's reasoning: mince fine enough that any stray fine bones won't catch the throat.
3. The dressing. Fish sauce, lime juice, roasted chilli powder, toasted rice. Taste as you go — every source aims at the same three points: sour, salty, hot. Nothing sweet.
4. The herbs. Fold through the spring onions, coriander, sliced jinda chillies and kaffir lime leaves — last, so they stay bright.
5. The table. Serve with hot sticky rice and raw vegetables — cucumber, yardlong beans, cha-phlu leaves — the way every Thai source serves it. The herbs are the vegetable course; the rice is the fork.

Where Thai Sources Disagree

How Western Versions Get It Wrong

• "Larb spice mix" with cumin and cinnamon. Laab is four seasonings — roasted chilli, toasted rice, lime, fish sauce — plus herbs. Cumin has no place in it; the earthy-nutty backbone comes from the toasted rice alone.
• Skipping the toasted rice. Without ข้าวคั่ว the dish isn't larb, it's just dressed minced fish. The rice is the texture, the aroma and the name of the technique.
• Cooking the fish in the dressing. Boiled or pan-sauced catfish tossed with herbs is not this dish. The fish meets the fire dry, on a grill or in a dry pan, and is dressed off the heat — that's what keeps it from turning to a fishy paste.
• Grilling, then flaking while it's still blistering. It sounds fussy but it matters: flaking hot fish makes the meat mushy and wet, and the dressing slides off. Aroifin's tip — wait until just warm — is the difference between larb and catfish sludge.
• Serving it as a lettuce-cup starter. Laab is a main course, eaten with hot sticky rice and a plate of raw vegetables. The lettuce is the spoon, not the point.
• Sweetening it. Seven of the eight Thai recipes we found season nothing sweet. A sweet "catfish salad" with sugar or sweet chilli sauce has left Isaan entirely.

UK Ingredient Notes

• Catfish: walking catfish isn't sold fresh in UK shops, but basa (pangasius) fillets — a farmed Vietnamese catfish from the same family, mild and sweet — are in every supermarket. Grill or griddle the fillets, then flake; the fine-bone step disappears with fillets.
• Toasted rice (ข้าวคั่ว): make it, don't buy it — toast raw sticky rice in a dry pan over medium heat, shaking constantly, until deep golden, then pound or pulse to a coarse powder. Two tablespoons for this recipe.
• Pla ra (ปลาร้า): bottled at Thai grocers. If you follow the Mahidol village pot, boil it with lemongrass and water first, as the source does.
• Kaffir lime leaves: fresh at Thai grocers in season, frozen year-round — both slice fine for this dish.
• Sticky rice: soak, then steam in a proper sticky-rice basket or a muslin-lined steamer. Jasmine rice will do, but the Isaan table wants glutinous.
• Chillies: red bird's eye from any supermarket replaces jinda; for the chilli powder, use roasted chilli powder (พริกป่น) from a Thai grocer rather than the raw Western kind.
