Description

Tom Kha paste is lesser-known than all the other Thai curry pastes. It is crucial to create a tasty base for the world-famous Thai chicken coconut soup, Tom Kha Gai.  Make this authentic recipe using two easy methods! 


Ingredients

Scale
  • 2 teaspoon salt
  • 1/4 cup lemongrass, finely chopped
  • 2 teaspoon galangal, finely chopped
  • 1/4 cup shallot
  • 1 tablespoon coriander seeds
  • 1/2 teaspoon whole white peppercorns
  • 1 tablespoon kaffir lime zest. Or 5 kaffir lime leaves, finely chopped
  • 1/4 cup cilantro stems chopped small. Or 3 cilantro roots, finely chopped.
  • 3 tablespoons lime juice. About 1 large lime


Instructions

Easy Tom Kha Paste Method with a spice grinder 

  1. Gather the Ingredients. Collect the essential ingredients, fresh galangal, kaffir lime leaves, lemongrass, cilantro stems or roots, shallot and fresh lime juice. These can be found at your local Asian stores.
  2. Prepare the Ingredients. Finely chop the galangal root to enhance its flavors. Slice the kaffir lime leaves into thin strips for even distribution. Crush the lemongrass to release its fragrant oils.
  3. Grind to a smooth paste. Put everything in a spice grinder or a small food processor and grind until you have a smooth paste. That's it! Super easy!

Traditional Tom Kha Paste Method

  1. Pounding the spices. In a mortar, grind the ground coriander seeds and white peppercorns with a pestle until the seeds are finely crushed. 
  2. Pound the herbs. Combine the chopped galangal, lemongrass, and cilantro roots. Add one tablespoon of lime juice to help turn the blades of the spice grinder. Pound until you have a paste. 
  3. Add shallot and kaffir lime zest or leaves and pound until a smooth and consistent paste forms. The key to making a smooth paste is not to add more than 3 ingredients to pound at one in the mortar.
  4. Season the paste. Add the salt and the rest of the lime juice to the paste, balancing the flavors according to your preference. Now is a good time to add more heat, too, if you prefer some. Use ground white pepper or crushed red peppers as much as your taste bud prefers! That's it! Enjoy. 
  5. Store Your Homemade Tom Kha Paste. Transfer your freshly made Tom Kha Paste into an airtight container and refrigerate it for future use. It will be your culinary secret to unlock the authentic taste of Thai food in your kitchen.

Notes

  • Never use ginger as a substitute for authentic Thai curry pastes. It will change the flavor and fragrance of the recipe entirely.
  • Garlic is never used in Tom Kha paste as the soup doesn't have garlic in it. But if you plan on using the paste for marinating or stir-frying, add 2 tablespoons of chopped garlic to this recipe. 
  • You'll need a small food processor to make this Tom Kha paste recipe. If you don't have one, use a spice grinder to make 2 batches, then combine them in a bowl.
  • Double up on the recipe; your small food processor will work great. 
  • Feel free to customize your Tom Kha Paste to match your preferences. You can adjust the spice, sourness, and sweetness levels by modifying the ingredients. 
  • Experiment with palm sugar or coconut sugar for a unique twist.
  • Add fresh or dried Thai chilies if you'd like some heat in your paste!
