Butterfly popcorn is a type of popcorn that expands into irregular, butterfly-like shapes when popped. This variety is known for its light and airy texture, making it a popular choice for snacking. The unique shape allows it to hold seasonings and toppings well, enhancing its flavor. Unlike mushroom popcorn, which pops into round, compact shapes, butterfly popcorn is more delicate and can break easily. It is commonly used in movie theaters and at home for making flavored popcorn snacks, such as cheese or caramel popcorn, due to its ability to catch and hold coatings effectively.
