Thai cuisine has been shaped by centuries of cultural exchange, trade, and migration. Its distinctive flavors and techniques are the result of a complex history that integrates local innovations with influences from neighboring countries, colonial traders, and global connections.
Early Influences
- Indigenous traditions: Thailand’s fertile land and tropical climate provided a wealth of fruits, vegetables, herbs, and fish. Early diets emphasized rice, freshwater fish, and seasonal vegetables.
