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 is really better described as four regional cuisines corresponding to the four main regions of the country:
Northern,
Northeastern (or
Isan),
Central and
Southern. Southern
curries, for example, tend to contain
coconut milk and fresh
turmeric, while northeastern dishes often include
lime juice. Thai cuisine has been greatly influenced by its neighbors, especially India, China, Malaysia, Laos. Many dishes are in fact Chinese dishes adopted to local tastes.
