Red Wine "Vinaigrette"
This is a variation on Patricia Wells' classic vinaigrette, in which leftover bits of red wine are reduced and used in place of vinegar. The reduced wine adds a sweeter, less acidic quality to the dressing. Use any combination of leftover wines for this, including red, white and rose. Use this especially when you are serving a salad with cheese, for the dressing is very wine friendly since there is no hint of acidity to fight with the wine.
The dressing can be stored at room temperature or in the refrigerator for several weeks. Shake again at serving time to create a thick emulsion.
