om Tam is one of the most popular foods among Thai people for its fiercely spicy and sour flavors. Som Tam, which literally means "Sour Pounded", is a spicy salad made from a mix of fresh vegetables including shredded unripened papaya, yardlong beans and tomato. Som Tam is unique that the spicy dressing and salad vegetables are pounded and mixed in the mortar using a pestle. Somtam is usually served with grilled chicken and sticky rice. Som Tam is good for your health that it contains no fat, low calorie and high vitamins. This is a truly authentic Thai dish that will make a great impression. The only reason why I’m ranking Som Tam at No.7 (though it deserves higher rank) is its strong spiciness that might leave your tongue burned and swollen. Just say "Mai phed" (not spicy) to your waiter if you really want to try.
