Instructions

  1. In a small saucepan, bring the sake to a boil over medium heat and cook for a few seconds to allow some of the alcohol to evaporate.
  2. Add the remaining ingredients and bring the sauce to a gentle simmer. Reduce to low heat to maintain the gentle simmer and cook for 5 minutes.
  3. Remove the saucepan from the heat and allow the mentsuyu sauce to cool down for at least 5 minutes – you can leave it for longer if you have more time.
  4. Drain the liquid through a fine mesh strainer to remove the kombu and katsuobushi.
  5. Your mentsuyu is ready to use. To store the mentsuyu, transfer it to a clean jar or airtight container and refrigerate for up to 4 weeks.

Notes

  •  
  • I adapted this mentsuyu recipe from the all-purpose soup base in Gohan: Everyday Japanese Cooking by Emiko Davies. It’s an excellent resource for anyone interested in Japanese home cooking.
  • For vegan mentsuyu: Swap the katsuobushi for rehydrated dried shiitake mushrooms. Rinse 3 dried shiitake mushrooms to remove any grit. Then place them in a bowl and cover with water. Leave the mushrooms to rehydrate for an hour before you start the recipe. Then follow the recipe using the rehydrated mushrooms instead of katsuobushi.
  • For the quickest mentsuyu: Substitute the kombu kelp and katsuobushi with a teaspoon of dashi powder and mix to combine. There is no need to simmer or strain.
  • Mentsuyu is a concentrated soup base that you need to dilute before using. For a cold dipping sauce, start with 1 part mentsuyu to 2 parts cold water. And for a warm noodle soup base, start with 1 part mentsuyu to 3 parts hot water. Taste and adjust the ratio of water to mentsuyu sauce.
  • Keep the spent kombu and katsuobushi in an airtight container and store it in the refrigerator for a week or in the freezer for up to a month. Use it to make furikake seasoning (recipe from Just One Cookbook). Or finely chop the katsuobushi and kombu, then mix it with a splash of toasted sesame oil, toasted sesame seeds and a sprinkle of togarashi (or chilli flakes). Generously spoon this condiment over rice and noodle dishes for an instant flavour boost!
