1. First thing to do is put of water in a pot to boil.
3. Take your stalks of lemongrass, and first tear off the outermost leaf and throw it out. Then, I like to use a mallet to lightly pound the lemongrass to release the flavors.
4. Take of the root part of galangal, and chop it into slices.
5. break lime leaves just tear them which is going to help release their flavor. Then just slice it guinea-peppe
8. Throw the lemongrass, galangal, kaffir lime leaves, and chilies into the water. You can put on the lid just so it starts to boil and release all the herb flavors quicker.
9. Now prepare your shrimp . I used freshwater shrimp(goong mae nam), I first chopped off all the tentacles.
10. Boil your soup with all the herbs in it for about 10 minutes, and you can go ahead and toss in the shrimp and turn the fire to low.
11. Then add your mushrooms, which you should pre rinse beforehand.
12. Take tomatoes and two small white onions and slice them into wedges . Then go ahead and add them to the tom yum.
13. If you’re using shrimp for this tom yum recipe, you might get some foam build up on top of your soup,in which case you can just lightly skim it off the top and toss it out.
14. Boil the tom yum for about 2 - 3 minutes.
15. Next, add about 6 tablespoons of fish sauce ,2 teaspoons of sugar , and squeeze lemon juice . You may need more of each, but start with that.
16. Boil your tom yum for another minute or so and then turn off the heat. The mushrooms and onions should be soft, and then it’s ready.
18 Make sure you taste test until your tom yum is perfectly sour and salty. You might need to add more fish sauce, sugar, or lime juice.
19. Finally chop up a handful of fresh cilantro, throw it in the soup, and give your tom yum a final stir. The cilantro taste fresher and more vibrant
20 You now have Tom yum goong
