                                Though often mistaken for a common leafy green, sorrel (Rumex acetosa) is actually a perennial herb that belongs to the buckwheat family. With a distinctive lemony flavor, this plant has a long history in European and Asian cuisines, offering a zesty punch that differentiates it from other herbs.
