This sweet, creamy drink is named after the long-winged seabirds that breed off the Pacific coast of South America. It uses a sugarcane-based liqueur called Cana Manabita that is produced in Ecuador. If you cannot find Cana Manabita, Brazilian Cachaca is a nice substitute. Or, as a third option, you could use a good-quality rum (though it won't produce exactly the same taste as either of the South American liqueurs). The datbase doesn't recognize Cana Manabita, so I hope I don't confuse anyone by the way I had to list that ingredient.
