Neccio, also called niccio, ciaccio, or cian, is a galette made with chestnut flour, typical of some mountain zones of Tuscany and Emilia, in Italy, and on the island of Corsica, in France.
Today people tend to consider neccio a dessert, but peasants once used to eat it with savory food.
The Italian government has declared neccio a Prodotto agroalimentare tradizionale ("traditional Italian regional food") of Tuscany.
