Mentsuyu (noodle soup base)

TIME15 minutes MAKES500ml PORTION

Mentsuyu is a concentrated Japanese soup seasoning, that is used to season almost everything — from yaki udon, to hot noodle soups like kake udon and kake soba.

To use it as a hot noodle soup base, dilute it with 4 parts water for 1 part mentsuyu (the resulting broth is then known as kaketsuyu).

INGREDIENTS

  • 125ml (1/2 cup) sake
  • 250ml (1 cup) soy sauce
  • 250ml (1 cup) mirin
  • 10g katsuobushi (dried bonito flakes)
  • 10g kombu (dried kelp)

STEPS

  1. Add all ingredients to a medium saucepan. Over medium-low heat, bring the mixture to a boil.

  2. Allow it to simmer for 5 minutes, before turning off the heat and allowing it to cool for another 5-10 minutes.

  3. Strain through a fine-mesh sieve.

NOTES

  • The mentsuyu can be stored in the fridge for a month.

  • The used kombu and katsuobushi can be stored in the refrigerator for a week or in the freezer for up to a month.
