Linguistic Note: Sauce d'arrachides

A very good question...why is it called ¨sauce d'arrachides¨ and not ¨sauce de cachuettes¨? In France, peanuts go by the latter name; in Cameroon, for agricultural reasons, their identity is different. Arracher means ¨to pick out of the ground,¨ so arrachides are those nuts that are harvested from the earth. In Cameroon. Voila!
