zest of 1 lime
Lime zest contains concentrated vitamin C, antioxidants, and beneficial plant compounds from the essential oils. However, typical usage amounts (from one lime) provide minimal caloric or macronutrient contribution to a dish.
About
Lime zest refers to the colored outer rind of the lime (Citrus aurantifolia or Citrus latifolia), a small citrus fruit native to Southeast Asia. The zest consists of the thin, oil-rich epidermis layer that contains concentrated flavor compounds, distinct from the white pith beneath it. Limes themselves are small, round citrus fruits with thin skin ranging from green to yellow at maturity, with tart, acidic juice and aromatic qualities. The zest contains limonene and other volatile oils that provide bright, intensely citrusy and slightly floral notes. Persian limes and Key limes are the most common culinary varieties, with Persian limes being larger and more readily available in Western markets.
Culinary Uses
Lime zest is valued for imparting concentrated citrus flavor without the acidity of lime juice, making it essential in both sweet and savory dishes across multiple cuisines. In Asian cooking, it features prominently in Thai curries, Vietnamese pho, and Southeast Asian marinades. Western applications include cocktails (particularly margaritas and daiquiris), baked goods, glazes, desserts, and seafood dishes. The zest is typically removed using a microplane or fine grater and added at the end of cooking or as garnish to preserve its volatile aromatic oils. It pairs well with chilies, garlic, cilantro, coconut, and fish.
