The popcorn is often seasoned with sea salt and sometimes enhanced with parmesan cheese or other spices to complement the truffle's unique taste. This snack has gained popularity in recent years, especially in upscale movie theaters and gourmet food shops. It offers a luxurious twist on traditional popcorn, making it a favorite for those looking to indulge in a flavorful treat while enjoying a film or social gathering.
