This is one of my “desert island” foods. I am absolutely addicted to this soup and these flavors. The bright, clean taste of lime, ginger and cilantro and the exotic coconut milk and red curry paste is divine.
Red curry paste is available online on Amazon and this particular brand is the best and will keep in the fridge for months. They also have green and yellow pastes. I have all three on the go all the time.
If you don’t have the Keffir lime leaves, then use lime zest, but I highly recommend you go out and buy a Keffir lime tree and keep it in a pot. There is nothing like the flavor of those leaves.

1 tbsp coconut oil
2 tbsp grated fresh ginger
1 stalk lemon grass (pound the white ends to release the flavor)
2 tsp or more, of red curry paste
4 cups chicken broth
3 tbsp Thai fish sauce (Asian section in supermarket)
1 tbsp coconut or palm sugar. (optional)
3 (13.5 oz ) cans coconut milk
1lb chicken breast sliced thin
1/2 lb fresh shitake mushrooms, sliced
2 tbsp fresh lime juice
2 Keffir lime leaves, very finely chopped, or the zest of 1 lime
1/4 cup chopped fresh cilantro
salt, to taste

Heat the oil in a large pot over medium heat.
Saute the chicken pieces till done, add the ginger, lemongrass and curry paste and cook, stirring for 1 minute.
Stop,    inhale,    the aroma!
Slowly pour the chicken broth over the mixture, stirring cnstantly.
Stir in the fish sauce and coconut sugar and simmer for 15 minutes.
Stir in the coconut milk and mushrooms and cook and stir until the mushrooms are soft, abut 5 mins.
Stir in the lime juice, and zest or finely sliced (julienned) Keffir lime leaves.
Season with salt, garnish with cilantro.

Serve!
