What it is

Key limes are a variety of lime, smaller and more tart than Persian limes, with a more intense aroma. They are believed to have originated in Southeast Asia and are now grown in tropical and subtropical regions, including Florida, Mexico, and the Caribbean. Key limes are typically used fresh or as juice.

Why it's used

Key limes are primarily used to add a distinct tart and aromatic flavor to foods and beverages. Their juice and zest are common ingredients in desserts like key lime pie, as well as in marinades, sauces, and cocktails.

Health notes

Key limes are recognized by the FDA as Generally Recognized As Safe (GRAS) when used as a flavoring agent. They are a source of vitamin C and antioxidants. JECFA has evaluated citric acid, a component of lime flavor, and set an acceptable daily intake. No specific evaluations or limits have been set by major international bodies for key limes themselves.

Allergen info

Key limes are not derived from any of the nine FDA major allergens. They do not contain gluten.
