This recipe comes from The Geometry of Pasta, many thanks to Caz Hildebrand and Jacob Kenedy for their kind permission to reproduce this recipe for everyone to try! The name for this particular pasta shape means 'strangle-priests'! Think of a shape like a small end of twisted rope. Specialist Italian delis stock it usually, but the authors of the book won't be going on house-to-house searches to check you are using the authentic shape for your supper!
