Tom Yum is one of the best known Thai dishes, a spicy, sour, and aromatic soup that is traditionally served with rice. It consists of shallots, lemongrass, fish sauce, minced fresh ginger or galangal, shrimps, mushrooms, kaffir lime leaves, lime juice, and minced Thai chili peppers.
Usually served as an appetizer, tom yum is traditionally garnished with coriander leaves on top. Due to its popularity, different versions of the soup started to appear over the years, such as tom yum gai, with added chicken, and tom yum talay, with mixed seafood.
