Key Limes

Key Limes

EverydayFresh

Key limes are a small, aromatic citrus fruit native to the Florida Keys, known for their intense tartness and floral acidity compared to common Persian limes. These golf ball-sized fruits feature a thin, yellowish-green rind and juicy pulp that’s prized in baking and mixology, most famously as the essential ingredient in Key lime pie. Their fresh juice and zest provide a concentrated source of vitamin C and deliver a brighter, more complex acidity than standard limes.
