juice of two lemons

Lemon juice is the liquid extracted from the fruit of Citrus limon, a small acidic citrus fruit native to Asia and cultivated worldwide. The juice comprises approximately 5-8% citric acid by weight, giving it its characteristically tart, acidic flavor profile, along with subtle floral and bitter notes. Fresh lemon juice is extracted by pressing or squeezing the fruit, typically yielding 2-3 tablespoons (30-45 ml) per medium lemon. The juice is composed primarily of water, citric acid, ascorbic acid (vitamin C), and various volatile compounds that contribute to its distinctive aromatic quality.

Common varieties affecting juice quality include Eureka lemons (high acidity, good juice yield) and Lisbon lemons (similar profile, slightly sweeter). Both possess pale yellow color and contain small seeds that should be strained before use in refined applications.

Lemon juice functions as a primary acidulant and flavor enhancer across global cuisines. It is essential in emulsifications (vinaigrettes, mayonnaise), brightens vegetable and seafood dishes, and provides the acidic component in marinades and ceviche. In baking, it reacts with baking soda for leavening and balances sweetness in desserts. Mediterranean, Middle Eastern, and Asian cuisines rely heavily on lemon juice for balance and depth. It prevents enzymatic browning in cut fruits and vegetables, and serves as a natural preservative. Fresh juice is preferred to bottled for superior flavor complexity, though bottled juice offers shelf stability and convenience.
