Mentsuyu (noodle soup base)
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).
