Casatiello is a the most famous Easter bread in Italy. Typical of Naples, it is served on Easter morning with cheese and cured meat. It's a rich bread made with rustic ingredients as the tradition calls for, and is decorated with the classic "trapped" eggs.
This traditional bread calls for ciccioli, pressed cakes of fatty pork typical of old rustic Italian cuisine. They are made by compressing, drying, and aging fatty, leftover pieces of pork. They are very hard to find, just replace with salami chunks.
