Kettlecorn is a form of popcorn which is made with both salt and a sweetener, creating a very distinctive flavor. This dish originated in Colonial America, where it became quite popular, and it spread to some parts of Europe, especially Germany. Kettlecorn actually briefly fell out of favor in the United States before experiencing a resurgence in the late 20th century, perhaps as part of an overall renewed interest in traditional American foods. Kettlecorn can be found at many fairs and social events, and it can also be made at home, either from scratch or from popcorn making kits.
Popcorn is an ancient New World treat. Archaeological expeditions have uncovered the traces of popcorn popping in settlements which are thousands of years old, suggesting that Native Americans were quite familiar with the properties of popping corn. When colonists first reached the Americas, they were undoubtedly introduced to popcorn at a fairly early stage, and by all accounts it was a very popular novelty food, which was also served as a snack at theater and music performances.
