aurantifolia

Aurantifolia is a term that primarily refers to the key lime, scientifically known as Citrus aurantiifolia. This fruit is a citrus fruit, a hybrid of a citron and a mandarin orange. It is a small, round, green lime, typically 1-2 inches in diameter. The key lime is known for its highly aromatic and acidic juice, which is more tart and floral than that of other limes. Its essential oil is also widely used for its distinctive aroma.

The key lime tree is a small, thorny tree, typically growing to a height of 6-13 feet. It is native to Southeast Asia but is now cultivated in many tropical and subtropical regions around the world, including Mexico, Florida, and the Caribbean. The fruit ripens from green to yellow as it matures.

In culinary applications, Citrus aurantiifolia is famously used in key lime pie, a dessert originating in Florida. Its juice is also a key ingredient in cocktails such as the Mojito and Margarita, as well as marinades and sauces. The zest of the lime is also utilized for its fragrant oils. Beyond its culinary uses, aurantifolia has a history of medicinal applications in traditional practices, though scientific evidence for these uses is often limited. The term "aurantifolia" itself is derived from Latin, meaning "golden leaf," likely referring to the color of the fruit or the foliage of the tree.
