Kaffir lime: Origin 

 The word Kaffir lime comes from the island of Sumbawa, whose name was mispronounced by Western navigators. This island belongs to the Sunda archipelago, east of Bali, in the Molucca Sea. At the end of the eighteenth century, Pierre Poivre introduced it to the Indian Ocean, Mauritius, and Reunion. In 1824, it appeared in the catalog of the Montpellier botanical garden where Augustin de Candolle then gave it the name Mauritius Papeda.

This tree is from the Rutaceae family with evergreen foliage. From a botanical point of view, it is one of the oldest citrus fruits: the Papeda group. Its leaves are easily recognizable; the winged petioles are as large, or even more developed, than the leaf blades. The branches are slightly thorny. The flowers mainly appear in spring, and if fertilized, give a fruit that resembles a lemon, with a warty rind. The kaffir lime fruit turns yellow when ripe. The leaves and fruits are aromatic, rich in essential oils.

• The tree: it is small and thorny, hence its name Hystrix. 

• The leaves: Its leaves have the winged petiole characteristic of all Papedas.

• Fruit: it is spherical and has a diameter of 4-6 cm. It has a rough rind that distinguishes it. It somewhat resembles a lime and bergamot, but its taste is quite different.

A sparkling taste discovery

Kaffir lime is appreciated as much for its leaves as for its fruits, which are consumed in different ways and offer an exceptional taste experience:

• Flavor: a unique flavor distinguishing between the leaves and the fruits. The leaf will provide a delicate lemongrass or verbena scent. The zest, on the other hand, has a rather fruity, slightly tangy scent, similar to lime, coriander, or ginger.

• Culinary uses: Zests or fresh fruit can enhance your desserts and perfectly flavor your mousses, creams, or even sorbets. Finally, add it to your jams, compotes, or coulis; their flavors will be sublimated. Kaffir lime leaves are highly sought after by great chefs as they perfectly flavor sauces or slow-cooked meats.

• Drinks: It wonderfully perfumes your cocktails as a substitute for lime.

• Nutritional value: With only 22 kcal per 100g of Kaffir lime, it is a low-energy citrus fruit that will allow you to enhance your meals by very moderately increasing your caloric intake. Like its cousin the lemon, Kaffir lime has anti-inflammatory properties thanks to its vitamin C content. This vitamin will help you fight against winter ailments and is a very good antioxidant for the body.

• Essential oil: The fruit and leaf produce an essential oil whose scent is reminiscent of lemongrass. This oil is mainly composed of monoterpenes, beta-pinenes, limonenes, terpenes, cineoles, and finally citronellols, from which it derives its powerful fragrance.
