Thai Coconut Soup, or tom kha, is a classic Thai chicken soup that's so much more intensely flavored than most western soups, it'll wake you up, tingle your taste buds and make your nose run (in the best way.)
Put the chicken stock in a soup pot, along with the onion, ginger, stalk of lemongrass and sliced hot peppers. Simmer over medium low heat for about 15 minutes.
Add the coconut milk, pastes, fish sauce, and chicken. Let it simmer for another 5 minutes so the flavors can meld.
Add the lime juice, cilantro and salt to taste. Remove the lemongrass and serve.
