Ingredients

Vegan Fish Sauce Ingredients

  • ½ tablespoon chopped garlic (about 1 clove)
  • ½ tablespoon chili flakes (or substitute with 1 Thai chili)
  • ½ teaspoon salt
  • 2 tablespoons maple syrup
  • 1 tablespoon lime juice
  • ½ cup (125ml) hot water

Instructions

  1. Combine Ingredients: In a heat-safe bowl or mason jar, mix the chopped garlic, chili flakes, and salt thoroughly to evenly distribute the flavors.
  2. Add Liquids: Pour in the maple syrup, lime juice, and hot water over the mixed dry ingredients.
  3. Mix Well: Stir or shake the mixture well until all components are fully blended to create a flavorful vegan fish sauce.

Notes

  • The spiciness depends on the chili flakes used; fresh Thai chili can be used for a hotter sauce.
  • Store the sauce in a jar at room temperature for up to 3 days or refrigerate for extended freshness.
  • Maple syrup can be substituted with sugar or your preferred sweetener – start with a small amount and adjust to taste.
  • Lime juice can be replaced with light vinegar such as rice vinegar for a different tang.
