limes; cut into thin wedges

Limes are the small, round citrus fruits of the Citrus aurantifolia species (Persian lime) and related Citrus species, native to Southeast Asia and now cultivated globally in tropical and subtropical regions. These fruits feature thin, green skin (in unripe stages) or yellow-green when mature, with highly acidic, pale green flesh and a distinctive tart, bitter-sweet flavor profile. Key varieties include the Persian lime (most common commercially), Key lime (smaller, more aromatic), and the Kaffir lime (used primarily for zest and leaves in Southeast Asian cuisine). The high citric acid content (4-7% by weight) and volatile oils contribute to their characteristic sharp taste and pungent aroma.

Limes serve as a fundamental souring agent and flavor component across tropical and Latin American cuisines. They are essential in beverages (margaritas, mojitos, caipirinha), marinades (ceviche, cochinita pibil), and dressings (Vietnamese fish sauce-based preparations, Thai salads). Lime wedges are the classic accompaniment to Mexican dishes, seafood, and Asian curries, allowing diners to adjust acidity to taste. The juice brightens fish and seafood preparations, while zest adds aromatic complexity to both savory and sweet applications. Whole wedges are also muddled in cocktails or pressed into hot beverages.
