This is a mild but spicy chicken soup (it can also be made with shrimp, pork, beef or mushrooms).
Note the number of red peppers is a personal choice. It can be as few as half a chilli per diner, to as many as 8-10 per diner, but the dish should retain a balance of flavors and not be overwhelmend by the chili peppers. We suggest about 8-12 chili peppers for this recipe.
Heat the stock, add the lime leaves, lemon grass, galangal, fish sauce, and lime juice. Stir thoroughly, bring to a boil, and add the chicken and coconut milk. Bring back to the boil, lower the heat to keep it simmering and cook for about 2 minutes (until the chicken is cooked through).
