Thai cuisine refers to typical foods, beverages, and cooking styles common to the country of Thailand. Thai Cuisine is known for its balance of five fundamental flavors in each dish or the overall meal - hot (spicy), sour, sweet, salty and bitter (optional). Although popularly considered as a single cuisine, Thai food would be more accurately described as four regional cuisines corresponding to the four main regions of the country: Northern, Northeastern (or Isan), Central and Southern, each cuisine sharing similar foods or derived from those of neighboring countries. Southern curries, for example, tend to contain coconut milk and fresh turmeric, while northeastern dishes often include lime juice.
