Ponzu Sauce

This bottled sauce combines citrus-flavored vinegar with soy sauce. The citrus fruit is traditionally yuzu, a type of citron, but versions using lemon, lime, or sudachi (a tiny Japanese lime) are also found in Japanese stores. The ponzu sauce found in most Western markets is fine for serving with the Sukiyaki, where the refreshing and cleansing bite of the citrus perfectly offsets the fatty richness of the meat. Ponzu can also be used as a seasoning for grilled or fried fish, or in salad dressings for a vinegary, citrusy kick.
