Tangy, tempting, and tasty; citrus and micro citrus fruits are potent food sources available on the planet for human consumption. Besides vitamins, minerals, and antioxidants that can keep you in good health, citrusy fruits are laden with water, which is an essential component of life. Most citrus fruits have been domesticated by indigenous cultures in their respective areas since antiquity. All of them are loaded with antimicrobial, anti-inflammatory, antiseptic, and antiviral properties that can ward off many mild or chronic illnesses. From an array of various citrus fruit species on earth, finger lime, botanically known as Citrus Australasia, is a variety of micro citrus fruit from the Rutaceae family. This finger-like fruit which also is fondly called the caviar of fruit or caviar lime is a thorny shrub found in forests of Australia. Presently it is globally sought after for its bright colour, tangy flavour, and nutrient-dense qualities. Despite its recent rise to fame, (which is more so from the past two decades), finger lime has had an ancient history of being utilized for thousands of years by humans for many reasons. Though it is primarily an Australian Native, over six genetically diverse varieties in different sizes and colours are available in many parts of the world. It is also being grown in northern parts of America abundantly. In the modern-day, even Asian markets are flooded with this very sour yet succulent fruit.

The Finger Lime Plant
The finger lime plant is a medium-sized bush with elongated leaves found in Australian rainforests. The shrub bears edible fruits which are tiny spherical finger-shaped vessels sometimes slightly curved ranging from light pink or purple to bluish-green in colour. Filled with acidic juice, the fruit is an elongated version of the common lime that almost resembles a gherkin (a small type of cucumber that is pickled in Western countries). The fruit has a rugged texture. Finger lime flowers are generally white and light pink and bloom from February through April. Due to their flavor and bright colors, the herb and its fruits are adored in culinary creations by food lovers. Its sour taste and strong fragrance make it ideal to be used for cooking jams, garnishes, and sauces. It can also be added to many alcoholic and non-alcoholic beverages.
