This tree in its magnificence flourishes in the high valleys leading down from Benevento to the plain of Naples and furnishes the Sorrentine walnuts of commerce. These, unfortunately, instead of being sun-dried as in Apulia, are dried industrially, losing much of the flavour in the process. In the south, walnuts are regarded as vital winter fare rather than as festive treats. They are kept in large glazed earthenware jars and are brought out to end a meal while carrying on with wine.
See also Pollo colla salsa di noci; pesto made with walnuts instead of pine kernels; and conserve of green walnuts.
