A newer, non-traditional-yet-much-loved version of Tom Yam Kung has milk added to it. Evaporated milk seems to be the most common milk of choice. These days, when you order Tom Yam Kung at a Thai restaurant or food stall, you’d be asked whether you’d like your Tom Yam “Nam Sai” (clear broth) or “Nam Khon” (creamy broth). To make Tom Yam Kung Nam Khon (ต้มยำกุ้งน้ำข้น), simply follow the recipe below, replacing 1/2 cup of the broth with evaporated milk or half-and-half. Add the milk to the pot after the shrimp has been cooked. No need to bring the whole thing to a boil; simply heat it through. Some curdling may or may not occur; don’t sweat it.
