Sorrel

Common sorrel, Rumex acetosa, is a perennial member of the buckwheat family, related to docks and rhubarb. Its native range extends across much of Europe and temperate Asia, where it grows in meadows, grasslands, field margins, and other open habitats. Its arrow-shaped leaves have a sharp, citrus-like taste produced largely by naturally occurring oxalic acid.

Sorrel was eaten as both a gathered wild green and a cultivated garden plant. Its tartness made it especially useful in regions where lemons were once scarce or costly. European cooks folded the leaves into soups, sauces, purées, egg dishes, and fish preparations; in France, cultivated sorrel became particularly associated with refined green sauces and potages.

The plant traveled readily with settlers and gardeners, becoming naturalized well beyond its original range, including in North America. Related species also entered regional food traditions: French sorrel, Rumex scutatus, is prized for tender leaves, while sheep sorrel, Rumex acetosella, is a smaller, intensely tart relative. Caribbean “sorrel,” however, usually means the red calyces of roselle, Hibiscus sabdariffa, and is botanically unrelated.

Today sorrel remains a specialty crop grown by market farmers and home gardeners in Europe and temperate parts of the United States, including California, the Pacific Northwest, and the Northeast. It is usually used in modest amounts because of its concentrated acidity, lending soups, salads, sauces, and herb mixtures a clean, almost lemony lift.
