The small, intensely aromatic Key lime of South Florida — sharper and more floral than common limes — a citrus that flavors and preserves across Black Florida and Bahamian cooking. A vitamin-C and flavonoid powerhouse.
Key limes are inseparable from the Black Bahamian-Conch foodways of the Keys, where they grow in dooryards and flavor everything from conch to pie. They are a defining citrus of South Florida Black cooking.
Key limes are dense in vitamin C for immune function and collagen, and their citric acid both aids iron absorption from plant foods and helps prevent kidney stones by binding urinary calcium. Their flavonoids and limonene are anti-inflammatory and support healthy blood vessels. As a souring agent, Key lime juice lets cooks season with acid instead of salt — directly useful for blood pressure.
Use the fresh juice and zest to brighten fish, marinate meats, cure conch and ceviche, and finish greens and beans. As a salt replacement, a squeeze of Key lime adds brightness that makes under-salted food taste complete. The whole fruit can be juiced and frozen in cubes for year-round use.
