There are two kinds of ponzu. One is a citrus-vinegar mixture generally used as a cooking ingredient, and the other is a combination of soy and citrus. This is the latter type. Maroyaka (which in this context, means "mild") is a particularly delicate version using the fragrant Japanese citrus, yuzu (although on the English ingredient list, it just states "citrus" they probably didn't know how to translate it). Exquisite dipping or finishing sauce with seared or raw seafood, Japanese BBQ (yakiniku), hot pot and salads.
