lime juice or ⅛ tsp cream of tartar

CondimentsLime fruit peaks in availability during summer and early fall in most regions, though Persian limes are available year-round in most markets due to global cultivation. Mexican limes (smaller and more acidic) have a shorter peak season in late spring.

Lime juice is rich in vitamin C and citric acid, providing significant antioxidant content with minimal calories. A 100-milliliter serving contains approximately 11 mg of vitamin C and 2.7 grams of carbohydrates.

About

Lime juice is the freshly expressed or processed liquid extracted from the fruit of Citrus aurantifolia (Persian lime) or related Citrus species, native to Southeast Asia. The juice is characterized by its bright acidic profile with a pH typically between 2.0 and 3.0, driven primarily by citric acid content of 4-6% by weight. Fresh lime juice contains volatile aromatic compounds that dissipate quickly, contributing floral and slightly herbaceous notes alongside its distinctive tartness. Commercial lime juice is available both as fresh-squeezed and as bottled pasteurized or concentrated forms, with the latter containing added preservatives and lacking the complex flavor profile of fresh juice.

Culinary Uses

Lime juice functions as both an acidulant and flavor agent across global cuisines. In Latin American cooking, it is essential to ceviches, marinades, and cocktails like margaritas and mojitos. Southeast Asian cuisines employ it in salad dressings (nam pla), curries, and fish-based broths. The acidity denatures proteins—crucial in ceviche preparation—while brightening heavy dishes and emulsifying vinaigrettes. Lime juice is also used to prevent oxidation in guacamole and other preparations. Its acidic nature makes it suitable for baking applications where it provides lift in conjunction with baking soda.

Forms & Preparations

Fresh-squeezed juice — Extracted immediately before use from whole limes; retains volatile aromatics and maximum acidity, preferred for raw applications and cocktails.
Bottled pasteurized juice — Heat-treated and preserved, with extended shelf life; suitable for cooking where fresh aromatics are less critical, but with diminished flavor complexity.
Concentrated juice — Reduced and preserved lime juice requiring dilution; economical for bulk cooking and shelf-stable storage.
Freeze-dried powder — Dehydrated lime juice reconstituted with water or used as a dry seasoning; convenient for travel and long-term storage.
Lime zest — Grated colored outer peel containing essential oils; used as garnish or flavoring to complement juice or replace it in certain applications.
