tbs finely grated lime zest
Lime zest is rich in vitamin C and contains beneficial essential oils and antioxidants concentrated from the peel; it is very low in calories and contributes minimal nutritional impact per typical serving.
About
Lime zest is the colored outer peel of the lime fruit (Citrus aurantifolia or Citrus latifolia), a small citrus fruit native to Southeast Asia and now cultivated worldwide. The zest consists of the thin, oil-rich epidermis that contains the fruit's concentrated flavor compounds, distinct from the bitter white pith beneath it. Limes themselves are acidic citrus fruits with a sharp, tart flavor profile and range in color from green (immature) to yellow (fully ripe), though most culinary applications use green limes. Key varieties include Persian limes (larger, seedless, widely available) and Key limes (smaller, more aromatic, traditional to Caribbean and Southeast Asian cuisines).
Culinary Uses
Lime zest is used to impart bright, concentrated citrus flavor without the acidity of lime juice. It is essential in Southeast Asian, Latin American, and Caribbean cuisines, appearing in curries, marinades, desserts, beverages, and garnishes. Finely grated zest is particularly valued in baking (cakes, bars, cookies), cocktails, and delicate sauces where texture matters. It pairs well with fish, seafood, tropical fruits, and spicy dishes. The zest can be added directly to batters or doughs, infused into oils and vinegars, or used as a finishing garnish for visual appeal and aromatic intensity.
