juice of two limes

Lime juice is the freshly expressed liquid extracted from the fruit of Citrus aurantifolia (Persian lime) or Citrus latifolia (key lime), small citrus fruits native to Southeast Asia and the Caribbean respectively. The juice is bright green to pale yellow in color, intensely acidic with a pH typically between 2.0–3.0, and delivers a sharp, slightly bitter-sweet flavor profile characterized by citric acid content of 5–8% by weight. Persian limes are the most commonly cultivated variety globally and yield a milder, more universally appealing juice than the smaller, more intensely flavored key limes. The juice contains aromatic compounds including limonene and various aldehydes that contribute to its distinctive floral and herbaceous notes.

Lime juice functions as a primary acid component in cuisines worldwide, serving both flavor and functional roles. In Latin American cooking, it is essential to ceviches, marinades, and fresh salsas, where its acidity denatures raw fish proteins and brightens vegetable preparations. Southeast Asian cuisines employ lime juice in dipping sauces (nam pla), curries, and pho broths as a final souring agent. In mixology and beverage preparation, lime juice provides the acidic foundation for cocktails such as margaritas, daiquiris, and mojitos. The juice also acts as a preservative in cured and fermented preparations, and its acidity can be leveraged to balance rich, fatty, or spiced dishes across Mediterranean, Middle Eastern, and African cuisines.
