Key Lime
Description
Key lime (Citrus aurantiifolia) is a citrus fruit known for its intense, aromatic flavor and small size. Originating from Southeast Asia, it is now widely cultivated in warm climates, particularly in the Florida Keys, from which it gets its name. The fruit has a higher acidity, a stronger aroma, and a thinner rind than the more common Persian lime. Key limes are prized for their unique flavor, which is both tart and slightly sweet.
Common uses
Key limes are often used to add a tangy zest to various dishes and drinks. They can be found in marmalades, pastries, and other sweets, as well as in savory dishes. Their juice is frequently used to enhance the flavors of seafood and meats, while the zest can be a fragrant addition to spice rubs and marinades.
