Made from the nuts of the Argan tree, which is grown in south west Morocco, Argan oil has a rich nutty flavour and a high level of vitamin E.

The oil has a smoky flavour somewhere between walnut and sesame oil, and is used to finish cooked foods, such as fish, chicken and roasted vegetables. It also makes an excellent salad dressing and can be used in spreads. It has almost twice the level of vitamin E as olive oil, is rich in anti-oxidants and is 80% unsaturated.

London-based Wild Wood Groves has set up a production centre in the Argan region with a Moroccan company. The local Berber women, who harvest the nuts, benefit from good wages and working conditions.
