Bomba is a popular tapas tourists don’t usually order because they have never heard of it, but which the locals love. Claimed to have been invented in the Barceloneta district, this tapa is usually served by the unit. It consists of a ball of mashed potato with a heart of spicy minced meat, covered in breadcrumbs and deep-fried, so it looks rather like a round croquette. It is a little parcel of comfort and good as a tapa on its own or with something light like peppers or seafood. Bombas are really the only traditional Catalan tapas.
