This dish is from Spain. For authenticity, you should use Spanish smoked paprika of the variety called "Pimenton De La Vera" - Not the regular smoked paprika ('Zaar won't let me enter pimenton as an ingredient!) Pimenton De La Vera is a powder made of smoked and ground chili peppers. It is a specific variety of smoked paprika and is produced only in one region in the southwest of Spain. If you don't have access to it, try using the more readily available varieties of smoked paprika. This recipe is from the San Francisco Chronicle (1/10/06). I have not yet prepared it.
