Flavours from the South: Between seas, spices and traditions
For the past few weeks, we have been exploring Thailand through its regional cuisines. After discovering the mountainous and aromatic dishes of the North, the fresh and tangy flavours of the Northeast, and the refined royal cuisine of the Central Plains, we now head south. This lesser-known region reveals a powerful and contrasting gastronomy, shaped by the sea, the monsoon and centuries of cultural exchange.
Southern Thailand is a land of abundance. Surrounded by two seas, the region draws its identity from seafood and from the generous use of spices, herbs and fermented condiments. Thanks to its tropical climate, nature here never rests, and local markets overflow year-round with fish, prawns, herbs and tropical fruits.
But the richness of the South does not end with geography. It also lies in its history. Over the centuries, the southern provinces have welcomed a mosaic of influences. To the west, the Andaman coast saw Chinese and Indian traders arrive, leaving a lasting mark on local Peranakan cuisine. To the east, near the Malaysian border, Muslim culture introduced a repertoire of fragrant rice dishes, coconut-based curries and fermented fish sauces, a legacy of the ancient Sultanate of Pattani.
In this article, we explore how geography, climate and trade routes have shaped this distinctive culinary identity. We will see how Southern Thailand’s emblematic dishes, from the tangy Gaeng Som (sour fish curry) to the dry-fried Kua Kling with turmeric, express the strength and diversity of this region. Finally, we highlight its essential ingredients, such as fresh turmeric, petai beans and nam budu, that give Southern Thai cuisine its unmistakable flavour.
Between two seas: A land shaped by the climate
Southern Thailand stretches between the Andaman Sea to the west and the Gulf of Thailand to the east. This dual coastline explains the abundance of seafood in daily life. Mackerel, snapper, trevally and countless small coastal fish are at the heart of local cooking.
This richness is reflected in dishes like fried king mackerel with fish sauce (Pla Insi Tod Nam Pla) or sand fish with garlic and turmeric, whose golden marinade recalls the southern sun.
The monsoon rhythm also influences the cuisine: when the sea becomes too rough, fishermen turn to drying and fermenting seafood. This is how the famous shrimp paste (kapi) and the nam budu, a fermented fish sauce from the Deep South, became staples of the southern pantry.
Heritage of the Sultanate, Chinese influence and coastal life
The Sultanate of Pattani and muslim traditions
The once-independent Sultanate of Pattani left a profound culinary heritage. Its influence can be tasted in dishes such as Beef Biryani (Khao Mok Nuea), where cinnamon, cardamom and turmeric blend with coconut milk and yoghurt.
In southern markets, the Khao Yam Nam Budu, a vibrant herbal rice salad with fermented fish sauce, represents the region’s balance of acidity, saltiness and freshness. Colourful, fragrant and deeply local, it is both a daily food and a cultural symbol.
Other recipes reveal Malay inspiration, like the Beef Massaman Curry, where warm spices meet coconut milk and shrimp paste to create a rich, slow-cooked harmony.
Phuket and the Peranakan memory
On the Andaman coast, the island of Phuket became a centre of Baba-Nyonya or Peranakan culture, the result of centuries of Chinese Hokkien migration and intermarriage. The cuisine of Phuket combines Chinese techniques with Thai ingredients, producing dishes such as Moo Hong (braised pork belly in soy sauce) and Pad Mee Hokkien (Hokkien-style stir-fried noodles with seafood).
Phuket’s salads also showcase this freshness and balance, as in the pineapple salad with tamarind and chilli paste, where sweetness, acidity and heat merge in a perfect southern blend.
Southern Thai cuisine: Signature flavours and culinary identity
Southern Thai cuisine is known for its intense and bold flavours:
A high level of heat, thanks to the liberal use of bird’s-eye chillies,
A salty depth, from fish sauce, kapi and nam budu,
A clear tanginess, from tamarind, lime and green mango,
Very little sweetness, used only to balance.
The petai bean (sato), strong and pungent, is one of the region’s most distinctive ingredients. Stir-fried with shrimp and shrimp paste in Kung Pad Kapi Sato, it embodies southern cooking’s aromatic power.
Another classic, Kua Kling Nuea (dry-fried beef with turmeric and pepper), symbolises the home-style dishes of the South – intensely spiced, fragrant, and without sauce, yet full of warmth.
The iconic dishes of Southern Thailand
Sour curries and fiery heat
The Sour Curry with Pineapple and king mackerel (Gaeng Som Pla Insi) perfectly captures the southern palate: a broth without coconut milk, sharp with tamarind, red chilli and acidity.
Even more intense, the Gaeng Tai Pla, made with fermented fish entrails and grilled mackerel, stands as one of Thailand’s most powerful and complex dishes.
Seafood stir-fries and ocean flavours
The coastal markets of the South overflow with crab, squid, clams and scallops. Among the most beloved dishes are soft-shell crab stir-fried with curry, sweet calamari with lemongrass, and clams stir-fried with chilli paste, all simple yet technically precise recipes that depend entirely on the freshness of the seafood and the timing of the wok.
Soups and Southern broths
Kai Tom Kamin (chicken soup with turmeric) is a rustic and restorative dish, common in rural areas. Further south, one finds octopus with tamarind leaves and prawn soup with melinjo leaves, showcasing local greens and their subtle bitterness, unique to the Andaman coast.
Herbs, aromatics and condiments of the South
Turmeric, the Southern signature
No other region in Thailand uses fresh turmeric as abundantly. It colours curries, soups and stir-fries, and serves as both a spice and a natural preservative. Southern yellow fish curries with wild betel leaves or tree basil are perfect examples of this golden, lemony balance.
Nam Budu and kapi
Nam Budu, a fish sauce fermented for several months, is typical of the deep southern provinces of Pattani and Narathiwat. It is essential in Khao Yam Nam Budu, the herbal rice salad described earlier. Kapi, or shrimp paste, connects land and sea, a cornerstone ingredient in curries, stir-fries and even spicy dips.
From the South to the Andaman Sea: Continuing the culinary journey
Southern Thai cuisine stands apart for its aromatic strength and maritime soul. Between curries rich in turmeric, petai stir-fries and herbal salads with nam budu, it expresses the character of the South: vibrant, coastal and deeply rooted in tradition.
