Delicious and delightful popcorn is part of so many traditions. Popcorn balls at Halloween, Popcorn strings at Christmas, and Popcorn all year round at the cinema. Corn has played an important role in the diets of many cultures, and has spread to be a worldwide phenomenon since it was imported from the new world. So on Popcorn Day make sure you have yourself a great big bowl of this delicious treat. I don't really bother with it. I find the smell as you walk into a cinema puts me off.
