The traditional Thai cuisine was very different than the current one in a holistic perspective.
At some point in history the Thai nation started trading globally, directly or indirectly with Indians, Iranians, Arabs and also Portuguese who brought several plant species to Thailand which today some of their plant parts
use as fundamental ingredients in Modern Thai Cuisine; for example, from the Americas:
- Chilles
- Pappaya
- Corn
- Tomato
- Green eggplants
- Tapioca
- Taro
- Potato
And from other places:
- Japanese teas
- Roses (Gulab in Thai, as in Indian and Persian)
- Indian spices and legumes (as well as legume flours)
- Wheat flour (probably from China or Arabia) uses to make Thai breads
- Date palms used in cookies (probably from west China or Muslim states)
My problem
I didn't find a lot of clear information about the main ingredients of non globally influenced cuisine (before the Thais entered global trade).
I assume that this cuisine was overall cuisine was more similar to modern Cambodian and Vietnamese cuisine but it might be hard to prove it.
My question
What were the main ingredients of the Thai cuisine before global trade (before Thailand traded with any country outside south east Asia)? I thought Pad Thai was one but it feels to me controversial.
