Thailand’s most famous soup, I consider this the king of all Thai soups. One great thing about tom yum soup is its simplicity. From start to finish you can easily have this ready in about 20 minutes.
Bring the broth to a gentle boil in a large pot and add the lemongrass, galangal, kaffir lime leaves and simmer about 10 – 15 minutes.
Add the bird’s eye chiles, onions, tomatoes, and mushrooms, and simmer for 4-5 minutes.
Add ¼ cup fish sauce and ¼ cup of the lime juice, stir well and taste. If additional salty or sour flavor is desired, slowly add more of each, to taste.
Add the shrimp and simmer for 2 -3 more minutes, until the shrimp turn pink and are cooked through.
Ladle the soup into individual bowls and add any combination of the seasonings, to suit your own tastes.
For a more hearty meal, serve with jasmine rice on the side, optional.
