What is the difference between a Sfogliatelle and a Lobster Tail (Pastry)
The difference is that in sfogliatelle the filling is made of Ricotta cheese, while in the Lobster Tail the filling is made of French cream.

Lobster Tail is not something prepared in Italy; you find it on New York City. I had to ask to friend of mine living in USA, to know what Lobster Tail pastry is.
