This soup is served in Northern Italy on Santo Stefano (also known as St. Stephens Day or Boxing Day) and on New Year's Day. It makes a welcome change from all the special celebration food at this time of year. It is traditionally made with the Christmas capon carcass, but chicken stock works equally well. This recipe calls for cappeletti, which means "little hat". The difference between cappelletti, from Modena, and tortellini, from Bologna, lies in the stuffing and not in the form. According to the Modenese, cappelletti are shaped like hats: On the other hand, Giuseppe Cerri, whom the Bolognese credit with the happy invention of the tortellino, claimed to have been inspired by a vision of Venus’s navel.
