For years, I had been intrigued by this curious cake from Livorno (Leghorn), a dessert that features sweet egg threads on top – a sign that it was introduced by the egg-loving Portuguese Jews and marranos who were invited to settle in the city by the Grand-Duke of Tuscany in the sixteenth century. With the help of the Jewish merchants, Leghorn became one of the most important port cities in Europe (but also a center of the printing press), and became known as “the city with no ghetto”.
I was already familiar with the local cuisine, and decided to try my hand at this tart, which looked like no other. Unfortunately, the yolk threads proved to be a huge challenge: I didn’t seem to be able to control the flow through the colander (the tool of choice in all the books that listed the recipe). My Livornese friends couldn’t help either: apparently they had always encountered the same problem and ended up with a sticky blob or with burns… they said that they used to buy the cake for Shavuot and for Purim from a well-known patisserie, but that when the owner died his tricks were buried with him. I had to wait until the blogging and YouTube era to figure this all out, with the help of some non-Jewish foodies from Portugal, where threaded eggs are often featured on Christmas recipes… in particular, thank you chef Fernando Canales for teaching me that in the 21st century it would be silly to use a colander when most of us have easy access to a pastry syringe (or at least a large syringe to dispense pediatric drops)!
