Ingredients
  

  • 1 piece (3-5 inch / 8-12 cm) kombu seaweed
  • 1 cup (240 ml) soy sauce or tamari
  • 1/3 cup (80 ml) mirin
  • 1 cup (240 ml) fresh yuzu juice, or 1/2 cup each fresh lemon and lime juice
  • & Variations
  • For a deeper umami flavor, let the kombu steep in the soy sauce mixture in the refrigerator for up to 24 hours before gently heating.
  • Experiment with different citrus! Grapefruit, pomelo, or blood orange juice can create unique and delicious versions of this classic sauce.
  • Create a Lemongrass Ponzu: Simmer a crushed stalk of lemongrass with the kombu, using 3/4 cup (960 ml) mirin, 1/4 cup (960 ml) soy sauce, and 1/2 cup (480 ml) water. Strain and omit the citrus juice for a fragrant twist.
  • To make this recipe fully vegan, ensure your mirin is vegan-friendly or substitute with a simple syrup (equal parts sugar and water).

Method
 

  1. In a small saucepan, combine the kombu, soy sauce, and mirin.
  2. Gently warm the mixture over medium-low heat. It is crucial not to let it boil, as this can create a bitter taste.
  3. Remove the pan from the heat and let it cool completely to room temperature, allowing the kombu to infuse its savory flavor into the liquid.
  4. Once cooled, remove and discard the piece of kombu.
  5. Stir in the fresh yuzu juice (or the lemon and lime juice combination).
  6. Transfer the finished ponzu sauce to an airtight jar or bottle and store it in the refrigerator. For the best taste, allow it to come to room temperature before serving.
