March 19 is the saint feast, or name, day for St. Joseph (San Giuseppe in Italian) and it is father’s day (festa del papa) in Italy. Giuseppe, shortened to Peppino, Pino, Pina, Giusy (a modern variation) can also be a female name, as Giuseppina. Celebrating St. Joseph as Mary’s husband is marked on May 1.
Italy is a Catholic country and in Rome, within hearing distance of the Vatican, Catholicism is a part of daily life. Every day, at certain times of the day, the bells toll from all the churches, not just to mark services, but also to set their time.
It seems like there is a special pastry and/or food that one should eat for everything. For St. Joseph’s day, it’s a beignet filled with pastry cream. It is called “bigne di san giuseppe” or “zeppole.” There are many recipes online, but basically it’s a choux pastry (baked up like a white sauce to create rise instead of using a raising agent) which is then injected with pastry cream.
In pagan times, this is the day that marked the end of winter, so bonfires were set ablaze to clear away the old wheat fields. Maybe they started frying dough on these fires?
In Danish, a danish is a “viennese bread” because it was brought to Denmark in the 19th century by immigrants from Vienna. There are many names and many types of pastry sold in Denmark and the bakeries, although no longer on every corner, are still to be had (today, 7-11 bakes fresh every few hours).
