Kaeng Khae (แกงแค)

The Curry the Fence Grows

แกงแค is named not for a sauce but for its vegetables. TrueID's writers describe the classic: the wild greens gathered from around the house are called ผักครัวแค — the kaeng khae kitchen greens — cooked with a paste they describe as a northern laab paste with pla ra added, then built around chicken or pork. The curry then takes its meat's name: แกงแคไก่, chicken kaeng khae, and the pork and other versions that follow. It is the north's answer to "what shall we eat today" — whatever the garden answers.

The paste is where the region speaks. Mahidol's nutritionists pound dried chillies with makwaen and maklaep — the prickly-ash spices of the north — along with galangal, lemongrass, coriander roots and shrimp paste. TrueID's village version roasts the chillies first, uses yellow galangal and makwaen, and pounds chopped pla ra into the paste itself. The pot build then splits three ways: Mahidol fries chopped garlic golden, fries the paste, seals the chicken in it and simmers everything in pork bone stock; Wongnai's home cook simply fries a ready-made paste sachet with chicken and water.

And there is a third, wilder build. TrueID's rainy-season recipe replaces the usual greens with บุกลาย, the toxic arum stem, boiled in the paste broth until completely soft — the heat destroys the toxin, the author insists, and it must never be eaten undercooked — then finished with cha-om and cha phlu and served with hot sticky rice. Mahidol adds the health case for the everyday version: the greens make the curry high in fibre and, their analysis notes, notably high in antioxidants.

The Recipe (from Mahidol University's Institute of Nutrition)

The ready-paste home version (Wongnai): for 3–4 — 3 diced chicken thighs, a bunch of ivy gourd leaves, 5 long beans, 3 round aubergines, 6–7 oyster mushrooms, a pinch of kapok flower, 2 culantro stalks, 2 long chillies, one sachet of kaeng khae paste, shrimp paste, fish sauce and sugar; the paste is fried with the chicken, water added, vegetables in, ivy gourd leaves last. The village version (TrueID): a whole village chicken blanched and scorched, cut up and fried with a paste of 15 roasted dried chillies, yellow galangal, lemongrass, garlic, makwaen and a spoon of chopped pla ra, then boiled and finished with garden greens and a last-minute handful of toasted rice to thicken. The rainy-season bowl (TrueID): buk lai arum stems boiled in the pla ra paste broth until fully soft, then cha-om and cha phlu — gloves for the peeling, sticky rice on the side.

The Method

1. The paste. Pound the dried chillies, shallots, galangal, chopped lemongrass, coriander roots, makwaen, maklaep, salt and shrimp paste until fine. Mahidol's spice order matters — the makwaen and maklaep carry the northern note, not the chilli heat.
2. The garlic. Heat the oil in the pot and fry the chopped garlic until just golden, then add the paste and fry until fragrant. The garlic fry comes first — it is the base the paste blooms in.
3. The chicken. Add the meat and stir until coated and cooked through, splashing in a little stock if it starts to stick. TrueID's village cooks do the same khua — frying paste and chicken together — in the same pot.
4. The stock. Pour in the pork bone stock, stir and bring to the boil. This is Mahidol's signature move; Wongnai and TrueID use plain water instead.
5. The hard vegetables. Add the slow-cooking vegetables first: dried hed lom mushrooms, green peppercorns, young galangal, long beans, pea aubergines, small bitter gourd, hyacinth beans and round aubergine.
6. The quick greens. When those soften, add the fast-cooking greens: phak phet shoots, saed phangphon leaves, chilli leaves, mint and cha phlu.
7. The last leaf. Cha-om goes in dead last, then the pot comes off the heat. Serve with rice or sticky rice; the greens should still hold their shape, the broth bright green and clear.

Where Thai Sources Disagree

How Western Versions Get It Wrong

• Adding coconut milk. Kaeng khae is a clear, brothy curry. Coconut milk never enters the pot in any Thai source; adding it produces a southern-style curry with the wrong name.
• Reaching for red curry paste. The paste is laab-style, built on makwaen and maklaep or yellow galangal — not the red paste's cumin-and-coriander chassis. Red paste gives a completely different nose.
• One vegetable, briefly. The vegetables are the dish. Eight to ten greens, staggered by cooking time, is the entire structure — a version with two vegetables is a different curry.
• Boiling the greens soft. Quick greens go in last and cha-om goes in dead last, off the heat while everything is still bright. A long simmer turns the curry to green sludge.
• Fearing the pla ra. Half the Thai sources put it in the paste; skipping it is fine, but the fermented fish is part of the dish's range — a bottled spoonful is the authentic option for the houses that use it.
• Undercooking the buk lai. If you attempt the arum-stem variant, boiling until fully soft is non-negotiable — raw or undercooked buk lai is toxic. Unsure? Make the chicken version.

UK Ingredient Notes

• Kaeng khae paste: ready-made sachets (Lobo and similar northern brands) are stocked by Thai online grocers in the UK — Wongnai's home version is built on one.
• Makwaen and maklaep are not exported; a small pinch of Sichuan peppercorn nods at the prickly-ash note without pretending.
• Cha-om, cha phlu, phak phet and saed phangphon are rare in the UK; young spinach, pea shoots and watercress fill the quick-greens slot, and coriander leaves stand in for culantro.
• Dried hed lom mushrooms: dried shiitake from any supermarket is the workable stand-in.
• Green peppercorns and kapok flower: skip if absent — fresh green peppercorns appear at Thai grocers in season, kapok flower does not travel.
• Pla ra: bottled and shelf-stable at Thai grocers; a tablespoon is all the paste needs if you want the fermented build.
