A herb that belongs to the buckwheat family which grows abundantly (it is a weed) in meadows in most parts of Europe. It's cultivated as a vegetable with leaves that are shaped much like those of spinach.
Sorrel ranges from pale to dark green in color and grows 2 to 12 inches in length. It has an acidic sour taste that can be used to flavor cream soups, accompany meats, or fill omelets and breads. Fresh sorrel is available in limited supply year round with the peak season in springtime when it is often used in salads or cooked as a vegetable.
