Mantecol is the brand name of a typical dessert of the cuisine of Argentina, a sort of semi-soft nougat made from peanut butter. It was originally created and marketed in the 1940s by the confectionery company Georgalos, founded by a Greek immigrant, Miguel Georgalos, who took the inspiration in a dessert of Greek cuisine, the halva.
Mantecol is very popular in Argentina, where it is used as daily candy (especially between the months of December and February), as well as classic dessert of the Christmas table.
