3 Servings

Ingredients

Base Ingredients:

  • 6 tablespoons water
  • 2 tablespoons granulated sugar
  • 1.5 tablespoons freshly squeezed lime or lemon juice
  • 2 tablespoons fish sauce

Optional Ingredients:

  • 1 garlic clove finely minced
  • 1 Thai bird’s eye chili finely sliced

Instructions
 

Dissolve the Sugar

  1. In a medium mixing bowl, combine 6 tablespoons of water with 2 tablespoons of granulated sugar. Stir well until the sugar is fully dissolved. If needed, heat a small portion of the water beforehand to help expedite the dissolving process, then mix it with the remaining water.

Add the Citrus Juice

  1. Gradually add 1.5 tablespoons of freshly squeezed lime or lemon juice, stirring continuously. Taste as you incorporate the citrus to ensure the desired level of tanginess is achieved. The mixture should have a mild tartness similar to a well-balanced lemonade.

Incorporate the Fish Sauce

  1. Slowly add 2 tablespoons of fish sauce to the mixture while stirring. Adjust the amount if necessary, depending on personal preference. The sauce should have a slightly bold taste on its own, as it is designed to complement lightly seasoned dishes.

Add Aromatics (Optional but Recommended)

  1. For additional depth of flavor, stir in minced garlic and finely sliced Thai chili. The garlic will infuse into the sauce over time, enhancing its richness, while the chili adds a subtle heat. If serving to guests, consider offering these as optional add-ins.

Serve and Enjoy

  1. Once all ingredients are well combined, allow the sauce to sit for at least 5 minutes to let the flavors meld. Serve immediately as a dipping sauce for spring rolls, grilled meats, or vermicelli bowls.
