Argan oil comes from the nuts of the Argan tree which grows exclusively in the south western part of Morocco. Nearly all the available argan oil is produced by a Berber women's co-operative called Targanine. The fruits of the tree are green, and resemble large, slightly rounded olives. Inside the fleshy covering is a hard shell containing up to three kernels from which the oil is extracted. The oil was extracted after the kernel has been roasted, ground and mixed with water to form a dough. It is recommended that the oil is added to foods which have already been cooked to add flavour and perhaps very sparingly in salads. It should not be used for frying.
