Mentsuyu dashi and soy sauce seasoning for noodle soup and more

Updated: Apr 30, 2020

Mentsuyu is litteraly means noodle soup. The liquid diluted with water is used for noodle soup. It contains umami taste from dashi stock and good balance of soy sause and sweetness of mirin. The mentsuyu also can be used as a convenient seasoning because the mixture contais dashi stock, soy sauce, mirin, sake and sugar. There are various recipes of mentsuyu including the ingredients, seasonings' ratios and the taste. There are various kinds of bottles of Mentsuyu in grocery market shelfs in Japan. We often find mentsuyu in recipe generally, that's mean mentsuyu is now national seasoning.

I teach how to make dashi stock in my cooking class for making miso soup, however in fact, many Japanese use instant dashi powder or saches for making miso soup, not makind the dashi stock from the scratch.

We often use dashi stock beside miso soup recipe, such as vegetable mixture "aemono" and savory egg custard. The dashi stock flavor enhances the taste of the dishes because the dashi stock contains rich Umami flavor. When the recipe calls small amount of dashi stock, I would use mentsuyu for instead of fresh dashi stock.

I saw and occationally bought mentsuyu in grocery store in NY and Chicago, I believe it was a Whole Foods Market, but I also made the seasoning at home.

Home made mentsuyu is much more flavorful, rich in umami,fresher taste and less expensive than the premade bottle.

Here is the recipe for about 200 ml Mentsuyu
