Number of tons of panettone produced in Italy this holiday season. The traditional Italian sweet bread studded with citron looks like a turban. The bread is said to have been invented in Milan in 1853. Yet, four hundred years earlier, panettone was mentioned in a manuscript belonging to Milan’s House of Sforza, a ruling family. Italians eat panettone (with coffee) for breakfast or (with wine) as a snack. One U.S. retailer alone—Eataly—is expected to sell 160,000 panettones from its flagship New York store this season.
