Rich in vitamin C and citric acid, with modest amounts of potassium and antioxidant compounds. The high acidity aids digestion and mineral absorption.
About
Limón refers to the small, green citrus fruit native to Southeast Asia, botanically classified as Citrus aurantifolia (Persian lime) or sometimes Citrus × limonia (Spanish lime), though the term varies by Spanish-speaking region. The fruit is roughly 1-2 inches in diameter with thin, bright green to yellowish-green skin, pale green to yellow flesh, and a sharp, acidic juice with citric acid content of 4-8%. In Latin America and Spain, "limón" typically denotes what English speakers call limes or key limes, characterized by their intensely tart, herbaceous flavor profile. The tree is small and thorny, thriving in warm climates, and the fruit does not fully sweeten as it ripens—it transitions from green to yellow while maintaining acidity throughout its maturity.
Culinary Uses
Limón is essential in Spanish and Latin American cuisines, used as both a flavor enhancer and acidifying agent. The fresh juice is squeezed onto ceviches, tacos al pastor, and seafood dishes to provide acid and brightness. Whole limes are halved and served as condiments for beverages, soups, and grilled meats. Limón is fundamental to Mexican marinades (mojo de ajo), Peruvian ceviches, and Caribbean cocktails, where its acidity "cooks" raw fish. The zest is used in salsas, rubs, and desserts. Beyond juice, the whole fruit appears pickled or candied, while the leaves flavor broths and beverages throughout Latin America.
