Ingredients (tbsp=15ml, cup=250ml)
  • 250g/0.6lb bonito fillets , cut into 2cm/¾” cubes (note 1)
  • 1 tbsp julienned ginger
  • 2 tbsp soy sauce
  • 2 tbsp mirin
  • 2 ½ tbsp sake
  • ½-1 tbsp sugar
  • 2 ½ tbsp water
  1. Boil water (not in ingredients) in a saucepan. Add bonito pieces and cook for about 30 seconds or so until until the surface of the fish pieces becomes completely white. Drain.

  2. Add the Sauce ingredients, blanched bonito pieces and ginger in a saucepan and cook over medium heat.

  3. Cook for 10–15 minutes until the sauce almost evaporates.

  4. While cooking, occasionally shake the pan so that the sauce coats bonito pieces evenly. If necessary, use a spatula to turn the bonito cubes over to get the sauce coating on all sides of the cubes.

  5. Turn the heat off. Serve warm or at room temperature.
Recipe Notes

1. Bonito is a seasonal fish and you may not find it at fish shops all year round. If you can’t find bonito, you can substitute it with tuna or king fish.

2. You can keep Bonito Kakuni in the fridge for about a week. It is also OK to freeze it.

3. Nutrition per serving as a side. Sodium is high as it is assumed that all of the sauce is consumed.
