shot fresh lime juice
Fresh lime juice is rich in vitamin C (ascorbic acid), providing approximately 15-20% of the daily recommended intake per ounce, and contains minimal calories (3-4 per tablespoon). It also provides small amounts of potassium, antioxidants, and flavonoids, while its high acidity enhances mineral bioavailability in foods.
About
Fresh lime juice is the liquid extracted from ripe limes (Citrus aurantifolia or Citrus latifolia), citrus fruits native to Southeast Asia and now cultivated globally. The juice is characteristically acidic with a pH of 2.0-2.6, containing approximately 4-6% citric acid by volume. Fresh-squeezed lime juice retains the fruit's volatile aromatic compounds, tannins, and natural sugars, delivering a bright, herbaceous tartness with subtle floral and grassy notes that distinguish it from bottled or concentrate forms.
Unlike processed lime juice products, fresh juice contains no preservatives and oxidizes relatively quickly, developing deeper, more muted flavors within hours of extraction. The juice extracted from Persian limes (larger, seedless varieties) differs slightly from that of smaller, seedier Key limes, with the latter offering a more intense, complex acidity.
Culinary Uses
Fresh lime juice functions as both a primary flavor agent and an acid-balancing component across global cuisines. In Mexican and Central American cooking, it is essential to ceviches, marinades, and salsas; in Southeast Asian cuisine, it provides the critical sour note in Vietnamese dipping sauces (nước chấm), Thai curries, and Laotian larb. It is fundamental to cocktails and mocktails—especially margaritas, daiquiris, and mojitos—where its acidity cuts through spirits and sweetness. Additionally, the juice is used to brighten soups, dress raw vegetables, cure seafood through acid denaturation, and prevent oxidative browning in fruits and vegetables. Its antimicrobial properties and acid content make it valuable for both flavor enhancement and food preservation.
