@mark.de.jose3: While there aren't specific, widespread dishes known for using gooseneck barnacles (percebes) in Vietnam, they are generally consumed in coastal regions, similar to how they are enjoyed in Spain and Portugal, a practice that involves simple preparations like boiling them to highlight their seafood flavor. However, Vietnamese cuisine is known for its resourcefulness and creativity with other types of small clams, such as "hến" (baby clams), which are featured in dishes like cơm hến (clams with rice) and bún hến (clams with rice noodles).
