Tom yum goong, Thai hot and sour prawn soup with mushrooms and coriander

Method

  1. 01

    Peel the prawns and set the meat aside. Do not throw away the shells.

  2. 02

    Fry the shells in a dry pot for 2 minutes until they turn pink and smell sweet, then add the water and simmer 15 minutes. Strain. This shell stock is what separates good tom yum from flat tom yum.

  3. 03

    Return the stock to the pot and add the lemongrass, galangal and lime leaves. Simmer 5 minutes.

  4. 04

    Add the mushrooms and crushed chillies and cook 3 minutes.

  5. 05

    Stir in the nam prik pao and fish sauce.

  6. 06

    Add the prawns and cook just 2 minutes, until they curl and turn opaque. Any longer and they toughen.

  7. 07

    Turn off the heat before adding the lime juice, so it stays bright and sour. Taste and balance: it should be sour first, then salty, then hot.

Cooking Tips

  • Fry the prawn shells and simmer them for the stock. That shell stock is the difference between good tom yum and flat tom yum.
  • Add the lime juice off the heat. Boiled lime juice turns dull and slightly bitter.

Ingredient Substitutions

  • Galangal is not interchangeable with ginger here, but ginger will do at a push.
  • Chicken or firm white fish can replace the prawns; use a light stock instead of shell stock.

What to Serve With It

  • Serve very hot with jasmine rice. The lemongrass and lime leaves are aromatics, not meant to be eaten.

Storage and Reheating

  • Keeps 2 days. Add fresh lime juice when reheating to bring the sourness back.
