Which of the following treats was invented in West Virginia?

The correct answer is pepperoni rolls, which were indeed invented in West Virginia. They originated in the early 20th century, particularly among Italian immigrant coal miners who needed a portable and hearty meal while working in the mines. The simplicity of the dish, with its dough filled with pepperoni, made it an ideal snack that could withstand the rigors of a long workday. This regional specialty reflects the unique cultural influences and practical needs of the people in West Virginia during that time.

Other choices, while popular, have origins that are not specific to West Virginia. Potato chips are attributed to a cook in Saratoga Springs, New York, as a method of serving potatoes. Cornbread is a traditional food found in various cultures, especially in the southern United States, signifying a broader regional practice rather than a West Virginia invention. Apple butter, though widely enjoyed in West Virginia, is a product that can be traced back to numerous regions in the U.S., with historical roots in early American colonies. Therefore, pepperoni rolls stand out as a distinct contribution from West Virginia's unique culinary heritage.
