The term "caritun" derives from the word "charity", since originally this very simple sweet was given to the poor by churches and confraternities.
In the past, Caritun was a sweetish bread prepared with the remains of the dough used to make bread, without adding butter, with a bit of sugar, and using the available fruits. Today, Caritun is made with butter, a lot of sugar, concord grape, and many grape seeds characterizing the final product and giving it a lively and characteristic color. Caritun is a round and flat focaccia, covered with icing or sugar grains and formed by a base of leavened dough covered by another sheet of dough, joined at the edges. Inside, concord grapes are arranged in a spiral shape. During the cooking, the latter release part of their juice, which unites with the dough. Sometimes concord grape is replaced with quinces. However, according to the traditional recipe, concord grape is the main ingredient of the filling. Since concord grape can be found exclusively in autumn, Caritun is a seasonal product: it is prepared only in autumn and in the early winter.
