What is ponzu? Is it some kind of soy sauce?

Answer 1

Ponzu (alternately spelled ponju or ponsu) is a citrus-based sauce commonly used in Japanese cuisine. It is very tart in flavor, with a thin, watery consistency and a light yellow color. Commercially available ponzu is generally sold in glass bottles, which may have some sediment at the bottom.
Ponzu is made by boiling mirin, rice vinegar, katsuobushi flakes, and seaweed (konbu) over medium heat. When cool the liquid is strained to remove the katsuobushi flakes and the juice of one or more of the following: yuzu, sudachi, daidai, and kabosu (Japanese citrus fruits), and sometimes also lemon, is added.
Ponzu shoyu is ponzu sauce with soy sauce (shoyu) added, but it is still widely referred to as simply ponzu.
Ponzu is traditionally used as a dressing for tataki (lightly grilled, then chopped meat or fish), and also as a dip for nabemono (one pot dishes) such as shabu shabu. It is also used as a dip for sashimi.
