Limes are rich in vitamin C and citric acid, supporting immune function and iron absorption. They also contain polyphenolic compounds with antioxidant properties.
About
The lime (Citrus aurantifolia, Citrus latifolia, and related Citrus species) is a small, green citrus fruit native to Southeast Asia, characterized by thin, smooth skin and acidic, aromatic flesh. The fruit typically measures 1–2 inches in diameter and contains high concentrations of citric acid (4–6% by weight), which imparts its distinctive sharp, sour taste. Key varieties include the Persian lime (Citrus latifolia), the most common in commercial cultivation, and the smaller Key lime (Citrus aurantifolia), prized for its complex flavor. The fruit's acidity mellows slightly as it ripens from green to yellow, though most culinary applications use mature green limes at peak juice yield.
Culinary Uses
Lime juice serves as a fundamental souring agent and flavor brightener across global cuisines, particularly in Latin American, Southeast Asian, and Mediterranean cooking. It is essential in beverages (margaritas, daiquiris, agua fresca), marinades for ceviche and fish preparations, curries, salsas, and as a finishing accent for soups and grain dishes. Lime zest provides aromatic oils used in baking, infusions, and garnishes. The whole fruit can be preserved, pickled, or dried for prolonged shelf life and concentrated flavor.
