Southeast Asian Salmon Soup This salmon soup is full of flavors commonly used across Southeast Asia, like lemongrass, lime leaves, galangal, bird’s eye chile, and fish sauce. The recipe calls for salmon heads and bones, which are usually very cheap at the grocery store and add so much flavor to the broth (you can pick off the meat when the soup is done cooking!). Galangal and lime leaves can be tricky to find, but they really make a difference in elevating the flavor so seek them out if you can!
