Mmmmmmmmmm … hardly anyone can resist the smell of freshly popped popcorn. Thoughts turn to days at the circus, afternoons at the county fair and nights in the back row at the movie theater, munching your way through memory after memory. For nearly 6,000 years, popcorn has played a part in the world’s cuisine. From hot rocks and religious ceremonies to microwaves and Friday night fright fests, popcorn may just be the world’s best-loved and oldest snack.
