Yuzu ponzu is a Japanese condiment sauce generally made from soy sauce or tamari, citrus juice, mirin, katsuobushi (bonito flakes), kombu and rice vinegar.

 It is very popular as a condiment for sashimi, shabu shabu, meat or fish tataki, gyoza, cold somen, tempura...

Ponzu is also excellent as a marinade or salad dressing. Kombu gives ponzu sauce the same umami flavor as dashi, while citrus juice and vinegar add acidity and soy sauce adds salt.

Word "ponzu" translates as "squeezed juice of sour oranges" in Japanese. Word comes from the Dutch "pons", meaning "punch", which later became ponsu, a "drink of mixed ingredients". Eventually, the suffix "su" was replaced by "zu", meaning "vinegar".
