Zea mays everta, commonly known as popcorn, is a special variety of corn that has a hard outer shell and a starchy interior. When heated, the moisture inside the kernel turns to steam, causing the kernel to explode and puff up into the fluffy snack we enjoy. This unique popping ability is due to its specific structure and moisture content. Popcorn is a whole grain and is often considered a healthy snack when prepared without excessive butter or salt. It is rich in fiber and low in calories, making it a popular choice for movie nights and casual gatherings.
