Easy Tom Yum Soup Recipe, Step by Step!

Step 9: Reduce heat to low. Add 1/2 can coconut milk OR 1/3 to 1/2 can evaporated milk. The latter is often used in Thailand, and is considered authentic for Tom Yum soup (strictly authentic Tom Yum with coconut milk is called 'Tom Kha', not 'Tom Yum'; however, these days most Thai restaurants don't bother with this distinction, given that coconut milk is really the ingredient that makes this soup sing!).

Tip: Try to use a good-quality coconut milk (not 'lite') for your Tom Yum. The fat in coconut milk is a healthy fat and is actually good for your heart. If you are concerned about your health, buy organic coconut milk, as pictured here.
