Ingredients

  • For the avocado:
  • 4 avocados
  • 4 tablespoons extra virgin olive oil
  • 1 tablespoon freshly grated wasabi or horseradish
  • 1 recipe ponzu sauce or good-quality store bought
  • Salt and pepper, to taste
  • For the ponzu sauce:
  • 1 piece kombu seaweed (3 x 2 inches) or 1 piece konbu (3 x 2 inches)
  • 1-1 1/2 cups bonito flakes (katsuobushi)
  • 3/4 cup soy sauce, plus 2 tablespoons
  • 3/4 cup lemon juice
  • 1/3 cup mirin, plus 1 tablespoon
  • 2 teaspoons sugar
  • 2 teaspoons rice vinegar

Method

  • Preheat your grill/grill pan as if you were cooking a steak.
  • Cut each avocado lengthwise in half and separate. Carefully remove the pit. With a large spoon, scoop the fruit out of it skin and brush each side with the olive oil. Season with salt and pepper.
  • Place the avocado flat side down and grill to mark. (The idea is to mark each avocado, not actually cook it.) Gently turn over and grill until barely warmed through.
  • Fill each cavity with the ponzu sauce and serve with freshly grated wasabi.
  • Combine all ingredients in a bowl and refrigerate for 1 to 2 days to develop taste. Strain well after 1 day. If you like more dashi flavor, then keep in refrigerator for 2 to 3 days and strain.
  • Store in the refrigerator for up to 6 months (don't worry, you will use this up very, very quickly).
