Sorrel

Sorrel (Rumex acetosa), also called common sorrel or garden sorrel, is a perennial herbaceous plant in the family Polygonaceae. Other names for sorrel include spinach dock and narrow-leaved dock ("dock" being a common name for the genus Rumex).

Sorrel is native to Eurasia and a common plant in grassland habitats. It is often cultivated as a leaf vegetable or herb.

Sorrel is a slender herbaceous perennial plant about 60 centimetres (24 inches) high, with roots that run deep into the ground, as well as juicy stems and arrow-shaped (sagittate) leaves which grow from a rosette. The lower leaves are 7 to 15 cm (3 to 6 in) in length with long petioles and a membranous ocrea formed of fused, sheathing stipules. The upper leaves are sessile, (growing directly from the stem without a petiole) and frequently become crimson. It has whorled spikes of reddish-green flowers, which bloom in early summer, becoming purplish. The species is dioecious, with stamens and pistils on different plants.

Several subspecies have been named. Not all are cultivated.

Rumex acetosa occurs in grassland habitats throughout Europe from the northern Mediterranean coast to the north of Scandinavia and in parts of Central Asia. It occurs as an introduced species in parts of New Zealand, Australia, and North America. It can grow in poor soil.

The leaves are eaten by the larvae of several species of Lepidoptera (butterfly and moth) including the blood-vein moth, aphids and by non-specialized snails and slugs.

Common sorrel has been cultivated for centuries. The leaves are edible when young but toughen with age; they may be puréed in soups and sauces or added to salad. The young shoots are edible as well, these and the leaves both being high in vitamin C and having a lemony flavor.

In India, the leaves are used in soups or curries made with yellow lentils and peanuts. In Afghanistan, the leaves are coated in a wet batter and deep fried, then served as an appetizer or if in season during Ramadan, for breaking the fast. In Armenia, the leaves are collected in spring, woven into braids, and dried for use during winter. The most common preparation is aveluk soup, where the leaves are rehydrated and rinsed to reduce bitterness, then stewed with onions, potatoes, walnuts, garlic and bulgur wheat or lentils, and sometimes sour plums.
