Made from plastic and/or metal, churreras usually come with a range of nozzles, which allow you to make various pasta strips, such as tagliatelli. My husband tells me that they would also be useful for piping mashed potatoes. They can be purchased from Orce Serrano Hams and Delicioso. We have a basic recipe for home-made churros.
