Tom Ka Kai (Chicken
Soup)
In Thailand, most tom
kha kai recipes typically include coconut milk, galangal, kaffir lime leaves,
lemongrass, Thai chilli peppers, coriander (or dill weed), straw mushrooms (or
shiitake or other mushrooms), chicken, fish sauce, and lime juice. Fried chillies
are sometimes added, and this creates a smoky flavour as well as texture, colour,
and heat; however, they are not added so much that they overwhelm the soup. The
key is to get a taste balance between the spices.
Ingredients:
2
tablespoons vegetable oil
2
boneless skinless chicken breasts, cut into 1 inch pieces
1/4
teaspoon salt
4
ounces fresh mushrooms, sliced (I use a stir-fry mix of mushrooms with
shitakes, oyster mushrooms, and portabellas)
3
green onions, sliced (divided)
1
stalk lemongrass
1
inch fresh galangal root or 1 inch gingerroot, grated
2
red chilies (more or less to desired heat level)
6
cups chicken stock (use good quality here)
1
(14 ounce) can coconut milk
1
1/2 tablespoons fresh lime juice
2
tablespoons fish sauce
1/2
teaspoon brown sugar
fresh
cilantro
fresh
basil leaf
Method:
1. In the bottom of a large soup pot, heat the
oil over high heat until very hot but not smoking. I often make this is a wok
on the stove.
2. Salt the chicken and add to oil, tossing to
brown all the pieces. Cook about 3 minutes or until outside is browned, but not
necessarily cooked all the way through.
3. Add mushrooms and toss. Allow to cook until
some of the moisture is cooked out and the mushrooms are soft. Turn down heat
to medium-low.
4. To prepare the lemongrass, slice and mince
the lower portion and reserve the stalk to flavor the soup. You can use a food
processor for this, or just mince it by hand. The woody upper portion of the
stalk will be removed later, so don't chop it up, simply score it by making a
few superficial cuts in it to allow it to flavor the soup.
5. Add the whites of the onions, reserving the
greens. Add the minced lower portion of the lemongrass, grated galangal, and
chilies. Toss until just warmed through.
6. Add the lemongrass stalk, lime leaves,
chicken stock, coconut milk, lime juice, fish sauce, brown sugar and remaining
onions, reserving just a few for garnish. Simmer over low heat for 15 minutes
to allow flavors to blend well.
7. Taste test and adjust flavors as follows:.
8. Not salty enough - add more fish sauce.
9. Too sour - add a little more brown sugar.
10. Too spicy - add more coconut milk.
11. Not spicy enough - add more chilies.
12. Ladle into 4 soup bowls and garnish with
remaining onion greens, cilantro, and basil.
13. Variations:.
14. Add more vegetables such as some sliced red
bell peppers with the mushrooms.
15. Serve over wide rice noodles for a main
dish serving.
16. Make vegetarian by increasing mushrooms in
place of chicken and substituting vegetable stock.
