Vinegar

  Two commonly used vinegars are red- and white-wine vinegar. White-wine vinegar is perfect for mild salad dressings or as a base for flavored vinegar, made by adding fruit or fresh herbs. Vinegar made from red wine has a more robust flavor than the white, and is often used as a marinade ingredient or in vinaigrette.   Vinegar should be stored in an airtight container in a cool, dark place. It will usually maintain its flavor for six months, but should be discarded at the first sign of mold.
