Lime is a term referring to a number of different fruits, both species and hybrids, citruses, which are typically round, green to yellow in color, 3–6 cm in diameter, and containing sour and acidic pulp. Limes are often used to accent the flavours of foods and beverages. These are also known as Kagzi Lime in North, North East and Central India. Some varieties are also known as scented lime. These have more scent than other common lime varieties. They are usually smaller than lemons, and a source of vitamin C. Limes are grown all year round and are usually sweeter than lemons.
Limes are a small citrus fruit, Citrus aurantifolia, whose skin and flesh are green in color and which have an oval or round shape with a diameter between one to two inches. Limes can either be sour or sweet, with the latter not readily available in the United States. Sour limes possess a greater sugar and citric acid content than lemons and feature an acidic and tart taste, while sweet limes lack citric acid content and are sweet in flavor.
In cooking, lime is valued both for the acidity of its juice and the floral aroma of its zest. It is a very common ingredient in authentic Mexican, Southwestern United States, Vietnamese and Thai dishes. It is also used for its pickling properties in ceviche. The use of dried limes (called black lime or loomi) as a flavouring is typical of Persian cuisine and Iraqi cuisine, as well as in Gulf-style baharat (a spice mixture that is also called kabsa or kebsa). Lime is an essential ingredient of any cuisine from India and many varieties of pickles are made e.g. Sweetened lime pickle, salted pickle, Lemon Chutney.
Lime leaves are also a herb in South, East, and Southeast Asia.
