Italian food is ubiquitous across the United States. Mall food courts have a requisite pizza place selling pepperoni-topped slices to hungry shoppers. Lasagna is a staple at the dinner table, and school cafeterias offer minestrone as the soup of the day. Bruschetta is on the appetizer menu at neighborhood bars, and coffee shops stock biscotti in the bakery case. At the grocery store, it’s easy to find prosciutto, gnocchi and dozens of flavors of gelato.
