Popcorn is a snack food that is made by popping the seeds of corn. The result is a fluffy and soft exploded kernel that can be eaten plain and on its own or dressed up with different ingredients. Many people enjoy adding salt and melted butter to their popcorn. Others like to sprinkle spices on it such as ranch powder or chili powder. You will also find it dusted with cheese or drizzled with caramel.
