Adjust the heat in this riff on Thai tom kha gai to your liking—use one chile for mild heat, two for medium, and three if you want sweat beading on your brow.
Packed with clear-your-sinuses heat, this comforting and spicy coconut soup will warm you up on cold nights. Inspired by the classic Thai soup tom kha gai, this version has pieces of salmon instead of chicken and uses easy-to-find ginger instead of traditional galangal root.
