What is a Sweet Lemon?

The term "sweet lemon" refers to a group of low-acid citrus fruits, most commonly identified with the species Citrus limetta. This fruit is not a true lemon but a distinct hybrid, which explains its unique flavor and low acidity. Known by a variety of names globally, including mosambi, sweet limetta, and Indian sweet lime, it is a staple in subtropical and tropical regions. Unlike the familiar sour lemon, the sweet lemon offers a mild, floral sweetness with only a subtle tangy undertone.

Origins and Distribution

The sweet lemon has ancient roots, believed to have originated in southern regions of Iran before spreading throughout the Mediterranean basin, the Middle East, and the Indian subcontinent.

  • Native to Iran and the surrounding regions.
  • Cultivated for centuries across the Mediterranean and South Asia.
  • Transported along trade routes, eventually reaching the New World.

Its widespread cultivation in different parts of the world has led to a variety of names and local adaptations. In India, for instance, it is known as mosambi or mausambi, and its juice is a hugely popular street vendor beverage.

The Unique Flavor Profile

The most distinctive feature of the sweet lemon is its taste, which is a stark contrast to the mouth-puckering sourness of a traditional lemon. Its flavor is described as mild, sweet, and floral. The low level of citric acid means the fruit lacks the intense tang found in other citrus, resulting in a flatter, sweeter profile that is often compared to a mix of limeade and pomelo. The juice is particularly famous for its unique characteristic of turning bitter just a few minutes after being exposed to air, so it is best consumed fresh.
