Ingredients

  • 1/3 cup fresh lime juice (2 or 3 limes)
  • 1 tablespoon unseasoned Japanese rice vinegar (optional)
  • 3 tablespoons sugar
  • 2/3 cup lukewarm water
  • 5 to 6 tablespoons fish sauce
  • 2 or 3 Thai or serrano chiles, thinly sliced
  • 2 cloves garlic, minced (optional)

Method

  • In a small bowl, combine the lime juice, vinegar, sugar, and water and stir to dissolve the sugar.
  • Taste and adjust the flavors to balance the sweet and sour as needed.
  • Add the fish sauce, starting out with 5 tablespoons and then adding more as your palate dictates, balancing the sour, sweet, and salty.
  • How much fish sauce you use depends on the brand and your own taste.
  • Aim for a light honey or amber color and a bold, forward finish.
  • Keep in mind that this sauce is typically used to dress dishes that include unsalted ingredients like lettuce and herbsingredients that will need an extra flavor lift.
  • When youre satisfied, add the chiles and garlic.
  • (If diners are sensitive to chile heat, serve the chiles on the side.)
  • Put the sauce on the table so that diners can serve themselves, or portion it out in advance for serving.
  • It may be prepared early in the day and left at room temperature until serving.
  • Small, cute dishes are good for plunging little morsels of food into sauce.
  • But if you are dunking a bundle of food wrapped in lettuce or a hand roll, you need shallow bowls three to four inches in diameter.
  • Look for limes with smooth skins.
  • They are juicier and easier to work with than fruits with dimpled, tough skins.
  • Before juicing, use your palm to roll the limes back and forth on a firm work surface.
  • This breaks down the membranes, which allows you to extract the maximum amount of juice from the fruit.
  • Because I like pulp in my sauces, I use an old-fashioned handheld reamer for juicing.
  • If your juicer filters out the pulp, start with a scant measurement of what is called for in a recipe, as you wont be working with the extra bulk contributed by the pulp.
  • You can always add more juice when making final adjustments.
