The bocconotto di Castel Frentano, also known as "castellino," is a traditional tartlet from the Castel Frentano in Abruzzo, Italy. The shortcrust pastry made using extra virgin olive oil is filled with a rich cream of dark chocolate, almonds, and cinnamon.
The pastry has a distinctive inverted cone shape and reveals a dark, compact filling with a fragrant aroma when cut. The dessert has roots dating back to the early 20th century, with variations passed down through generations. It is a recognized Traditional Agri-food Product (PAT).
