Watch this cooking tutorial to learn how to make coconut soup which is also know as tom kha gai. For this dish, you can either stir fry your meat or boil the coconut cream first.
Button Mushrooms (accidentally hit the wrong buttom and typed "buttom" in my video)
Tamarind Base (or you can use lime juice)
Chicken Soup Base (wouldn't need this if you replace water with chicken stock)
