The tom yum gai looks simple, but is packed with complex flavors of lemongrass, galangal, shallots and kaffir lime leaves that layer tightly on one another. The heat comes from toasted dry peppers and the holy basil makes that heat interesting. The lime juice keeps the soup sharp and interesting.
Tom yum gai is easier to make than tom yum goong for a couple reasons. Quality shrimp is hard to come by in the US. You can keep perfecting the tom yum gai’s flavors without impacting the chicken’s texture. Overcooked shrimp will turn hard.
