As we approached the 900th drink added to cocktail party, we knew wed need something appropriate for the occasion. As providence would have it, this lovely recipe for the white tie & tiara slid across our desk at cocktail party hq, complete with a difficult-but-not-impossible ingredient list and promising a heady bouquet of citrus and flowers. The recipe comes from the makers of grey goose le citron vodka (although it will work with any citrus vodka of decent quality). It specifically calls for white grapefruit juice, which we vehemently support. The pink stuff will do, and is certainly easier to find but the bitterness and complexity of white grapefruit truly sings in this drink, keeping the sweetness of the lychee juice and jasmine syrup in check.
