Ingredients

  • 6 tablespoons fresh lime juice (3 limes)
  • 1 tablespoon unseasoned Japanese rice vinegar (optional)
  • 1 tablespoon fine shrimp sauce
  • 3 tablespoons fish sauce
  • 2 1/2 tablespoons sugar
  • 1/4 cup water
  • 2 or 3 Thai or serrano chiles, thinly sliced (optional)

Method

  • In a small bowl, combine the lime juice and vinegar.
  • Whisk in the shrimp sauce, blending well.
  • Add the fish sauce, sugar, and water and whisk to dissolve the sugar.
  • Taste and adjust as needed to arrive at a pleasantly tangy, sweet, salty, pungent sauce.
  • A little more lime (up to 1 tablespoon) will tame the pungency and sweetness.
  • If the overall flavors are too intense, add water by the teaspoonful.
  • If you like shrimp sauce, whisk in more.
  • When you are satisfied with the balance, add the chiles and set aside for 30 minutes to let the flavors develop before serving.
  • Put the sauce on the table so that diners can serve themselves, or divide among individual dipping sauce bowls.
  • It may be prepared 2 to 3 hours in advance and left at room temperature until serving.
