This creamy soup is full of Thai flavor. Lemongrass, lime, coconut milk, ginger and cilantro elevate this soup to an exotic treat.
The ‘tongue of fire’ in the title refers to a variety of heirloom beans with that name, which have a meaty texture and an undertone of spice in them. They are firm like kidney beans – which you can use in their place if you can’t find the exotic ones.
In case it’s hard for you to find some of the more exotic ingredients near you, I have some easier-to-find substitutions below.
