Common Sorrel or Garden Sorrel (Rumex acetosa), often simply called sorrel and also known as Spinach Dock or Narrow-leaved Dock, is a perennial herb that is cultivated as a garden herb or leaf vegetable (pot herb). This is not related to Jamaican sorrel (roselle). Common sorrel has been cultivated for centuries. The leaves may be purÃ©ed in soups and sauces or added to salads and shav; they have a flavor that is similar to kiwifruit or sour wild strawberries. The plant's sharp taste is due to ascorbic acid. In Northern Nigeria, Sorrel is known as Yakuwa or Sure(pronounced suuree)in Hausa. It is also used in stews usually in addition to spinach. In some Hausa communities is it steamed and made into salad using Kuli-Kuli ( traditional roasted peanut cakes that its oil has been extracted), salt, pepper,onion and tomatoes. The recipe varies according to different level of household income.
