What is Thai food? Every country in the world has its own food profile. It reflects its culture, environment, ingenuity and values. In the case of Thailand, these words come to mind: intricacy; attention to detail; texture; color; taste; and the use of ingredients with medicinal benefits, as well as good flavor.But Thailand really is broken down into four distinct regions: the South, the Center, the Northeastern Isan and Northern Thailand. They all have different ethno-linguistic backgrounds, different food traditions, terroir and different ingredients that they have access to that have formed the cuisine.
