Mentsuyu is Japanese soup base used in soba and udon noodle dishes. It’s made from sake, mirin, soy sauce, kombu, and katsuobushi (dried bonito flakes).
There are two types of mentsuyu: kaketsuyu, which is poured hot over boiled noodles to make noodle soup, and tsuketsuyu which literally means “dipping soup” for chilled noodles.
Mentsuyu is usually sold concentrated, so dilute with water before using. The proportion of water used to dilute the soup base varies depending on the use. Usually 2-3 parts of water for 1 part of mentsuyu.
This mentsuyu recipe is also concentrated, so please adjust the soup base accordingly.
For convenience, you can purchase Mentsuyu bottle from Japanese (or Asian) grocery stores or online.
