Popcorn
Description
Popcorn is a type of corn (Zea mays var. everta) that expands and puffs up when heated. The kernel's strong hull contains the seed's hard, starchy endosperm with 14-20% moisture, which turns to steam as the kernel is heated. Popcorn is a popular snack enjoyed by people of all ages, known for its distinct popping sound and fluffy texture when cooked.
Common uses
Popcorn is typically eaten as a snack, either plain or flavored with a variety of toppings such as butter, salt, sugar, caramel, cheese, or spices. It is also used as a festive decoration during holidays like Christmas when it is strung on threads and hung on trees.
