The Clementine is often seen as a citrus fruit typical of the Isle of Beauty. A reputation that somewhat overshadows the Citron, this kind of large, bumpy lemon with a sweet and sour taste, cultivated on the island since the 1st century BC. It is one of the three original citrus fruits of the island according to INRA, and preparations based on Citron or candied Citron are part of Corsican gastronomic culture. The Clementine is said to have been discovered in Oran, Algeria, by Father Clément (hence its name). It results from the hybridization of a common Mandarin tree and a sweet Orange tree. A marriage that gives it a very sweet flavor and has made it a success.
The Clementine is seedless, unlike the Mandarin. It is a green fruit when ripe, which only turns orange due to the drop in winter temperatures.
Despite its "recent" discovery (early 20th century), it must be acknowledged that the Clementine is now the most cultivated citrus fruit on the island. Corsica is also the only French region to cultivate it. You know the trick: it is distinguished from Spanish Clementines by the fact that they are sold with their leaves...
It is precisely the leaves that are distilled to obtain Petit-grain, more precisely the leafy branches resulting from pruning the tree after harvesting in winter. (The extraction of the fruit peel yields the zest)
The fact that it is the leaves that are extracted gives a green and fresh aspect to the scent of this essential oil, which is highly appreciated for the calm it instills in the mind.
