Oil & Vinegar are a perfect match, they go together in pure harmony and can make any salad sing. Well the Salad Song - Oil & Vinegar Cruet Set ($25) may have something to with that. This unique porcelain cruet set holds your oil and vinegar separately in two vessels whose pouring spouts oddly resemble singing mouths apparently crooning to each other. I'm glad they appear to be so happy singing, because together they make such beautiful music salad dressing.
