Ponzu (Soya-bean Sauce with Citrus)

Ponzu is a kind of sauce that contains soya-bean sauce and “yuzu” juice. “Yuzu” is a citrus fruit that is very sour and has a nice smell. Ponzu is used when we eat “shabu-shabu”, boiled green vegetables, or pickles. You can easily find ponzu at supermarkets but very easy to make yourself. Fresh yuzu gives better flavor but you can also use bottled “yuzu” juice.
