Lime Fruit

Lime is a term referring to a number of different fruits (generally citruses), both species and hybrids, which are typically round, green to yellow in color, 3-6 cm in diameter, generally containing sour pulp, and frequently associated with the lemon.

The limes most commonly available commercially are the smaller, yellower Key lime (Citrus aurantifolia) and the larger, greener Persian lime (Citrus × latifolia). Key lime is an American retronym, as the original fruit known in English as a "lime" was Citrus aurantifolia. Other limes include the Mandarin lime (Citrus limonia), Kaffir lime (Citrus hystrix), the various Australian limes, Spanish lime (Melicoccus bijugatus), wild lime (Adelia ricinella), sweet lime (Citrus limetta), Palestine sweet lime (Citrus limettioides), and musk lime (X Citrofortunella mitis).

Lime fruit, and particularly their juice, are used in beverages, such as limeade (akin to lemonade). Alcoholic beverages prepared with limes include cocktails such as gin and tonic, margarita, mojito, and Cuba libre, as well as many drinks that may be garnished with a thin slice of the fruit or corkscrew strip of the peel (twist). One customary consumption of tequila is in shots accompanied by lime wedges and salt. Beer is often served with limes in Mexico, as well as some other countries. Lime juice is also used in commercial soft drinks.

In cooking, lime is valued both for the acidity of its juice and the floral aroma of its zest. It is used in tacos, Key lime pie, a traditional Florida dessert, and is a very common ingredient in authentic Mexican and Southwestern American dishes. It is also used for its pickling properties in ceviche. Additionally, the leaves of the Kaffir lime are used in southeast Asian cuisine.

In order to prevent scurvy during the 19th century, British sailors were issued a daily allowance of citrus such as lime (presumably Citrus aurantifolia), which led in time to the nickname "limey" for all Britons. It was later discovered that this beneficial effect derived from the quantities of Vitamin C the fruit contains.

Lime extracts and essential oils are frequently used in perfumes, cleaning products, and aromatherapy.
