Often, people describe Thai cuisine as a balance of sweet, sour, salty, spicy, and bitter flavors. It is a familiar and recognizable combination with a long history.

One of the biggest factors that contributed to the development of Thai food’s unique taste and its evolution throughout time is the centuries of trade, migration, and cultural exchange, including also cooking techniques, from different parts of Asia and even beyond.

Ayutthaya (Thailand) was founded in 1350; it soon became one of the world’s largest cities and was an extremely important connecting point between the East and the West, where foreign merchants would trade, live, and share cultures. – UNESCO World Heritage Centre

Yet wherever the ingredients may have come from and wherever the cooking techniques originated, all of them were incorporated into Thai cooking and, in time, they became Thai – they’ve become something recognizable and recognizably local.

But to truly (like ‘truly’ truly) understand that journey of some of Thailand’s most popular dishes, we have to go a bit back in time and check some events in history that made those dishes into what we love today.

Noodles

Noodles are part of everyday Thai eating, but when it comes to their history, we have to look at Chinese communities and, of course, the long tradition of trade and migration.

During those times, Chinese immigrants brought various noodle-making traditions to Thailand and the ingredients that go along with them.

Chinese immigration to Siam that has been occurring for at least 600 years helped introduce noodles (‘guay tiew’; the Thai term for noodles) into the Siam culture. – Cambridge, G. William Skinner

Dishes today, such as pad see ew and other varieties of noodle soup, are dishes that established Thai cuisine despite the fact that their historical connections came from outside Thailand.

Pad see ew is a good example of how a dish that has outside influences and origins can become local.

Stir-fried noodles, dark soy sauce, and vegetables are a popular combination in Thailand, yet those techniques and a good number of ingredients came from and are a reflection of Chinese culinary traditions. But it’s not just about transplanting dishes and cooking techniques; Thai cooks, of course, took those elements, but they also added and adapted them to suit local tastes and local ingredients.

This process created something new and something with its own identity.

Curry

When talking about curry, we talk about a lot of different dishes that come from all across Asia.

While South Asian influences were important and had a big role in popularizing certain spices and ideas, it was Southeast Asian ingredients and cooking methods that gave the Thai version its distinct taste and character.

Persian and Indo-Persian Muslim communities started moving to Ayutthaya around the 17th century; it is that culture that has introduced Persian culinary cuisine into Thai culture (e.g., massaman curry). – Encyclopedia Iranica

When you’re directly comparing Thai curry paste to Indian style spice blends, it’s easy to see the differences.

While fresh ingredients such as chilies, lemongrass, galangal, garlic, shallots, makrut lime leaves, and other aromatics can be pounded together in a paste, coconut milk, which is important in many Thai curries, gives it that extra richness while at the same time balancing heat and its aromatic ingredients.

Roti and the Influence of South Asian Communities

Another cuisine with origins all across South Asia and beyond is roti. Any visitors who come to Thailand will find roti as a common street food snack generally prepared with condensed milk, sugar, banana, or other toppings. So most of the time, it’s quite sweet.

Its presence in Thailand is connected in part to South Asian and Muslim communities. The Thai street-food version generally looks different from the roti that can be found in other places.

26 Muslim settlements represented six ethnic groups in Old Bangkok (1767-1910) – Persian, Arab, Indian, Cham, Malay, and Indonesian. This strong evidence suggests Roti became part of Thai culinary culture because of the influence of South Asian and Muslim communities in Thailand. – Journal of Siam Society

Food works as an interesting way of preserving history. Something like a simple noodle dish can tell a tale of migration. Curry can show centuries of trade and exchange. There’s a lot to it if we look closer.

Eating, apart from being fun, is a useful way of looking at that history. It’s not just about Thai food; we can take those same principles and apply them to any other country and any other aspect of their culture.

For example, if traveling to Kyoto (Japan), travelers can discover Fernwayer’s Kyoto craft experiences and see how traditions continue to evolve by doing deeply immersive and story-led cultural activities. Kyoto’s tea drinking culture helped develop industries such as ceramics, lacquerware, bamboo crafts, etc.

It’s the same in Thailand.

Royal dining has a massive influence on the traditional decorative ceramics (e.g., Benjarong) used even today throughout the country.

Every activity, every part of a culture shows its history and the steps before (and those that came after). It’s just up to us to discover it.

Conclusion

Thai food, like the cuisine of most other cultures, is one that is shaped by the history of different people, ingredients, techniques, and ideas. It shows the path of its people, and it shows another time.

Even something like chili peppers, now seemingly inseparable from Thai cuisine, arrived from another part of the world (the Americas via Portuguese traders during the 1500s).

Yet despite that, its influences remain strong in Thai cuisine. And not only that, but they help explain it and its history. The next time you are eating, remember there’s much more to the dish before you than meets the eye.

To find out more, all you have to do is simply ask and investigate a little, and who knows, you may discover a lot of interesting things.
