Thai Curries

Thai Curries

Thai curries (gaeng, แกง) are the emotional heart of Thai cooking — the dishes that demand the most skill, use the most ingredients, and deliver the most complex flavours. Unlike Indian curries (built on dry spice blends) or Japanese curries (roux-thickened), Thai curries start with fresh aromatic paste pounded in a mortar, then cooked in coconut cream to create something simultaneously rich, fragrant, spicy, and bright.

The Anatomy of a Thai Curry

Every Thai curry follows a similar structure:

1. Crack the coconut cream — Heat thick coconut cream in a wok or pot until it splits (the oil separates from the solids). This is crucial for developing flavour.
2. Fry the paste — Add freshly made curry paste to the cracked coconut cream and fry until fragrant (2–3 minutes). The paste should sizzle and release its aromatics.
3. Add protein — Chicken, pork, beef, prawns, or tofu. Cook briefly in the paste.
4. Add coconut milk — Thin coconut milk goes in to form the curry sauce.
5. Season — Fish sauce (salt), palm sugar (sweet). Adjust balance.
6. Add vegetables — Thai aubergines, bamboo shoots, long beans, etc.
7. Finish — Fresh Thai basil, kaffir lime leaves. Remove from heat.

The entire process takes 15–20 minutes — Thai curries are fast food made from slow ingredients.

The Major Curries

Gaeng Khiao Waan — Green Curry

The most popular Thai curry internationally and domestically. The green colour comes from fresh green chillies in the paste.

• Paste: Green chillies, lemongrass, galangal, coriander root, cumin, white pepper, shrimp paste, kaffir lime zest, garlic, shallots
• Character: Hot, aromatic, sweet-salty, herbal
• Typical proteins: Chicken (most common), beef, pork, fish balls, prawns
• Key ingredients: Coconut milk, Thai aubergines (pea aubergines and larger varieties), bamboo shoots, Thai basil, kaffir lime leaves
• Heat level: Medium-hot to very hot (the most chilli-forward of the coconut curries)

Gaeng Phet — Red Curry

Visually similar to green curry but with a different flavour profile — rounder, warmer, less sharp.

• Paste: Dried red chillies (not fresh), same base aromatics as green
• Character: Rich, warm, less aggressively herbal than green curry
• Typical proteins: Duck (classic pairing), chicken, pork, prawns
• Key ingredients: Coconut milk, bamboo shoots, Thai basil, pineapple (in some versions), kaffir lime leaves
• Variation: Red curry with roast duck (gaeng phet ped yang) is a Bangkok restaurant classic — the richness of duck fat with the warmth of red curry

Gaeng Massaman — Massaman Curry

Voted the "world's most delicious food" by CNN Travel (multiple years running). A deeply aromatic, rich, relatively mild curry with Muslim-Malay origins from southern Thailand.

• Paste: Dried chillies, lemongrass, galangal, plus warm spices: cardamom, cinnamon, cloves, star anise, cumin, nutmeg. This is the most "Indian-influenced" Thai curry.
• Character: Rich, mild (by Thai standards), warming, slightly sweet, nutty
• Typical proteins: Beef (classic), chicken, lamb
• Key ingredients: Coconut milk (generous), potatoes, onions, peanuts, bay leaves, tamarind
• Heat level: Mild — this is the Thai curry for spice-averse diners
• Origin: The word "massaman" likely derives from "Muslim" (Mussalman). The curry reflects the cuisine of Thai Muslims in the southernmost provinces, who blended Thai aromatics with Indian-Malay spice traditions.

Gaeng Panang — Panang Curry

A thick, reduced, intensely flavoured curry — more paste-forward than other coconut curries.

• Paste: Similar to red curry paste but with added peanuts and more kaffir lime
• Character: Dense, creamy, slightly sweet, with a pronounced kaffir lime fragrance
• Typical proteins: Pork, beef, chicken
• Key ingredients: Reduced thick coconut cream (less liquid than other curries), finely shredded kaffir lime leaves, peanuts
• Serving style: Often served as a thick sauce over rice rather than as a soupy curry
• Heat level: Medium

Gaeng Kari — Yellow Curry

The mildest and most approachable Thai coconut curry — influenced by Indian and Malay traditions.

• Paste: Dried chillies, turmeric (the dominant flavour and colour), curry powder influence, lemongrass, shallots
• Character: Mild, warming, golden, slightly sweet
• Typical proteins: Chicken, shrimp
• Key ingredients: Potatoes, onions, coconut milk
• Heat level: Mild
• Relation: Yellow curry is the base for khao soi (the northern egg-noodle curry soup)

Gaeng Pa — Jungle Curry

The outlier — no coconut milk. A thin, fiery, intensely herbal curry from the forests of central and northern Thailand.

• Paste: Fresh green chillies, wild ginger (krachai/fingerroot), green peppercorns, turmeric
• Character: Hot, sharp, clean, herbal — no richness to buffer the heat
• Typical proteins: Wild boar (traditional), chicken, pork, fish
• Key ingredients: No coconut; water or stock base. Loaded with vegetables: bamboo shoots, long beans, Thai aubergines, wild greens, green peppercorns, krachai
• Heat level: Very hot — the absence of coconut milk means nothing tempers the chilli
• Origin: Forest communities who didn't have access to coconut (a coastal crop)

Gaeng Som — Sour Curry

An acid-forward, thin, orange-coloured curry built on tamarind and turmeric.

• Paste: Dried chillies, turmeric, shrimp paste — simpler than most pastes
• Character: Sour, spicy, clean — refreshing rather than rich
• Typical proteins: Fish (most traditional), shrimp
• Key ingredients: Tamarind (the dominant flavour), vegetables (cauliflower, morning glory, green papaya, cabbage)
• Heat level: Hot (southern version) to medium (central version)
• Regional variation: Southern gaeng som is considerably spicier and more pungent

Gaeng Tai Pla — Fish-Organ Curry

Southern Thailand's most fearsome dish — a curry built on fermented fish entrails (tai pla), turmeric, and an unholy amount of chilli. The smell is commanding. The taste, for those who can handle it, is one of the most complex in Thai cooking.

• Not for beginners. This is the deep end.
• Eaten with rice and a selection of fresh vegetables to offset the intensity

The Curry Paste Comparison

Curry Etiquette

• Thai curries are spooned over rice, not dunked into
• Take a little at a time from the communal curry bowl — don't load your plate
• The curry should be saucy — it's meant to flavour the rice, not be eaten as a standalone stew
• At home, Thais often eat curry with a side of omelette (khai jiao) and fresh vegetables

Making Curry Paste at Home

The single most important factor in Thai curry quality is freshly made paste. Store-bought paste (Mae Ploy, Maesri) produces acceptable results, but homemade is transformatively better.

Essential equipment: granite mortar and pestle (krok sak). 20 cm diameter minimum. Available at Thai/Asian supermarkets internationally.

The pounding order matters — harder ingredients go in first:

1. Dried spices (peppercorns, cumin, coriander seeds) → pound to powder
2. Salt + dried chillies → pound to paste
3. Fresh chillies → add gradually
4. Hard aromatics (lemongrass, galangal, kaffir lime zest) → pound until fibrous
5. Coriander root, garlic, shallots → pound until smooth
6. Shrimp paste → incorporate last

Total time: 15–25 minutes of steady pounding. This is a workout.
