Sorrel
Rumex acetosa
Also known as: Rumex acetosa, common sorrel, garden sorrel
A perennial herb in the buckwheat family (Polygonaceae) — native to temperate Eurasia. The arrow-shaped leaves have an intensely sour-lemony flavor that comes from oxalic acid — making sorrel one of the few traditional Western herbs that delivers a pure acid taste from a leaf rather than a fruit. Foundational to French (*soupe à l'oseille*, *sauce verte*), Eastern European (Polish, Russian, Ukrainian *szczawiowa zupa*), and traditional British cuisine (the Tudor-era *green sauce*). The Jamaican-Caribbean 'sorrel' drink is unrelated — it's made from [[hibiscus]] flowers, not this plant.
Scientific
Rumex acetosa (family Polygonaceae — same family as [[buckwheat]] and rhubarb) is a perennial herb native to temperate Europe and northern Asia. The plant reaches 30–60 cm with characteristic arrow-shaped (sagittate) leaves and tall flower stalks producing small reddish flowers in midsummer.
The intensely sour-lemony flavor comes primarily from oxalic acid — the same compound that gives rhubarb stems their tartness. Oxalic acid content is high enough that sorrel should be consumed in moderate quantities; large amounts can stress the kidneys (oxalate binds calcium and can contribute to kidney-stone formation in susceptible people).
Related cultivated species:
- Rumex acetosella — sheep sorrel; smaller, often weedy
- Rumex scutatus — French sorrel; milder flavor, slightly more delicate
The Jamaican-Caribbean “sorrel” beverage — a foundational Christmas drink across the Caribbean and Caribbean diaspora — is made from dried [[hibiscus]] sabdariffa calyces, not from this plant. The shared common name is one of the more confusing botanical-name overlaps in English.
Cultural and culinary
European culinary uses are foundational:
- French — soupe à l’oseille (sorrel soup, often with cream); sauce verte (green sauce); fish preparations (particularly with salmon — the tannins-and-acid help balance the fish’s richness); omelette à l’oseille
- Eastern European — Polish szczawiowa zupa (sorrel soup, often with hard-boiled egg); Russian zelyonye shchi (green schi); Ukrainian zelenyy borshch (green borscht); spring foraging staple across the region
- British (historical) — Tudor-era green sauce and sallets (salads); medieval English foragers’ herb
- Vietnamese, Filipino — used in some regional sour-leaf preparations alongside more-common Asian souring herbs
The French sorrel-with-salmon pairing — saumon à l’oseille — is one of the canonical haute-cuisine preparations of the 1970s–1980s nouvelle cuisine movement; the brothers Troisgros’s 1962 Saumon à l’oseille des Frères Troisgros at their Roanne restaurant is one of the most-referenced single dishes of modern French cuisine.
Wild foraging
Wild sorrel (especially Rumex acetosella, sheep sorrel) is a common forageable plant across temperate North America and Europe. The leaves are immediately identifiable by their pure sour flavor — children sometimes encounter them in meadows and discover the surprising acidic taste. Spring is the traditional foraging time; the leaves become bitter as the season advances.
