Thai — Curries (No Coconut) Techniques

Gaeng hang lay is the flagship curry of Northern Thai (Lanna) cuisine — a slow-braised pork curry with Burmese and Shan culinary influences, distinct from all Central Thai curry styles. The paste incorporates dried chillies, lemongrass, galangal, shallots, garlic, and critically: ginger, turmeric, and curry powder — spicing that reflects Burmese gaeng hm (the direct ancestor). The broth uses tamarind rather than coconut milk; pickled garlic and palm sugar are added to balance the acidity and provide the characteristic sweet-sour note. The dish is traditionally cooked the day before, and like massaman, it improves dramatically with resting.

Gaeng leuang (yellow curry) is the Southern Thai counterpart to gaeng som — a no-coconut, turmeric-yellow, aggressively sour fish curry specific to the Gulf and Andaman coasts. Unlike the kari-style yellow curry (which is coconut-based and Indian-influenced), gaeng leuang is built on a paste of fresh turmeric, dried chillies, lemongrass, and kapi in a water-tamarind base. It is intensely sour, quite hot, and powerfully aromatic — the turmeric provides the yellow colour while fresh galangal and lemongrass provide the herbal backbone. Short mackerel (pla thu) or kingfish are the classic proteins; bamboo shoots, green papaya, or yard-long beans are the traditional vegetables.

Gaeng liang is the oldest Thai curry style — predating the arrival of chillies from the Americas, relying on white pepper for heat and dried shrimp paste for depth. It is a clear, fragrant broth cooked with seasonal vegetables: young marrow, baby corn, pea eggplant, and an abundance of fresh Thai basil or sweet basil added at the end. The paste is simple (dried shrimp, white pepper, shallots, kapi) and brief; the broth is water or a light pork stock; the cooking is fast. This is considered a healthy, restorative dish in Thai culinary tradition — its simplicity is intentional, its flavour is clean, and it is one of the few Thai dishes where the vegetable character is primary.

Gaeng om is the characteristic Northern Thai (Lanna) herb curry — a clear, aromatic broth loaded with dill, lemongrass, kaffir lime leaves, green onions, and various fresh and dried herbs that are not found in Central Thai curries. The paste base uses dried chillies, galangal, lemongrass, shallots, and kapi but no coconut milk — the broth is thin, herb-forward, and distinctly different from anything in Central or Southern Thai cooking. Dill (phak chi lao, or 'Laotian coriander') is the ingredient that most identifies gaeng om as Northern — its presence immediately locates the dish geographically. The protein is traditionally pork (including offal), venison, or freshwater fish.

Gaeng som is the defining curry of Southern Thailand — sour, fiery, and turmeric-gold, with absolutely no coconut milk. The broth base is tamarind water (or green mango pulp, or fresh sour fruit depending on season and region) seasoned aggressively with fish sauce and the deep-fermented kapi that characterises the South. White fish (typically snapper, grouper, or the more traditional platu — short mackerel) is the standard protein. The technique is simple compared to coconut curries — paste is fried briefly, tamarind water added, fish added, and the whole thing simmered for 10–15 minutes. Speed is part of the ethos. The acidity is non-negotiable and should be bold rather than restrained.

Gaeng tai pla is considered the most intensely flavoured of all Thai curries — built on tai pla, the fermented fish entrails and organs of small tuna or mackerel, it has a funky, deeply savoury, polarising depth that defines Southern Thai cuisine at its most uncompromising. The fermented tai pla (not fish sauce, not kapi — a specific product from the South) is cooked with dried chillies, lemongrass, galangal, and bamboo shoots or eggplant in a thin, sour broth. The flavour is described as intensely salty, fishy, sour, and complex — the fermented organ character dominates everything. This is regional cuisine at its most distinct and resistant to modification.

Jungle curry (gaeng pa, forest curry) is the roughest and most elemental of Thai curries — made without coconut milk (historically unavailable in the interior forest regions), with whatever protein and forest vegetables were at hand, and seasoned with fiery bird's eye chillies, fresh green peppercorns, and wild herbs. The curry paste base is closest to red curry paste but omits the cream-friendly spices (less galangal, no coriander seed) and amplifies the heat and herbs. Wild boar, fresh water fish, frog, or whatever forest animal was hunted are the traditional proteins; in modern cooking, chicken or pork are standard. The cooking liquid is water or broth — the dish should be assertively flavoured, herbaceous, and very hot.
