I think Thai food is the spiciest and consistently spicy across all their dishes too. The thing with Thais is that they use chilies in everything- soups, salads, noodles, curry and even in desserts. Often Thais eat ground red chilies and sugar with sour mangos. Also, something unique with Thai food is the way they pair the spicy, perfectly to my taste, with sweet and sour which I think makes Thai food amazing. The hottest dish that I have eaten in my years Thailand would be a very fiery som tam (papaya salad) or a larb gai ( spicy northern chicken salad). I love chilies and those two particular dishes had me sweating. By the way the best way to get rid of the heat is to drink dairy, milk or yogurt like the Indians do. The Thai serve lots of steamed rice or stick rice up north with their meals to help dissapate the heat. -Jim
