Sfogliatella (Neapolitan Layered Shell Pastry with Ricotta)
A stiff flour-and-water dough, rolled very thin, brushed with butter and wound into a tight log, gives this Neapolitan pastry its layers. Slices of the log are pushed open into shells and filled with ricotta, sugar, cinnamon and orange zest. In the oven the butter separates the layers so the outside shatters like glass. Cut the chilled log with one straight-down stroke so the layers on the cut face are not crushed.
