An unusual and versatile alternative to vinegar, verjuice--or verjus--is the golden juice of unripened green grapes. Delicate, sweet-tart, and clear, verjuice was very popular in the Middle Ages until it was eclipsed by the lemon. Because it shares the same acid base as wine, verjuice will not distort the essence of wine, the way a vinegar-based dressing may. Like lemon juice, verjuice heightens the flavors of soups and sauces, makes an excellent marinade, and may be used for cooking or deglazing. Refrigerate after opening.
Ingredients: Green Grape Juice of Périgord.
