History and traditions
Various species of sorrel were used medicinally from at least the 14th century, but it was always chiefly valued as a culinary herb, especially in France and Belgium, where it was even potted as a preserve for winter use. Recipe books of the 17th and 18th centuries reveal that sorrel was not just made into soup, but frequently served with eggs, put into a sweet tart with orange flowers and cinnamon, as well as being cooked as a spinach-like vegetable. John Evelyn considered that it should never be left out of a salad, lending it sharpness, as a useful substitute for lemons and oranges when they were scarce. He also wrote that it “sharpens appetite … cools the liver and strengthens the heart” (Acetaria, 1719). Culpeper recommended it for many medicinal purposes, including the breaking of plague sores and boils.

Sorrel adds a pleasant, lemony flavor to soups, sauces, salads, egg, and cheese dishes. But it is acidic and not recommended for rheumatism and arthritis sufferers. The leaves have the best flavor and texture in spring, before they become coarse and fibrous.
