When you think about it, few dishes are more American than a pepperoni pizza.
Both pepperoni and pizza are versions of Italian specialties that we as a nation have made our own. (In fact, there’s no such thing as “pepperoni” in Italy, and American visitors who order it there are often surprised and disappointed when what they end up with is peperone — bell pepper.) Few other cuisines are as widely popular as pizza, and pepperoni is one of the most widely popular toppings, no matter the regional style of pie they are decorating.
In our most recent ranking of the 101 best pizzas in America, more than 700 pizzas were considered by 78 pizza experts, who selected a wide variety of pies from all over the United States. There were a few pies that incorporated pepperoni, but it was usually not the starring ingredient. Take Eddie’s special at Eddie’s in New Hyde Park, New York — sausage, meatball, pepperoni, pepper, mushroom, and onion — or the deep dish with sausage and pepperoni at Pequod’s in Chicago, Illinois.
