It was historically used in various culinary traditions and is experiencing a resurgence in modern kitchens. Long pepper can be used in spice blends, pickles, and some traditional dishes to impart a unique and lingering heat. Its distinct appearance, resembling elongated catkins, adds visual interest to culinary creations.
