Make Sfogliatelle Shells With Puff Pastry
Preheat the oven to 355F (180C).
Start by dividing puff pastry dough in 6 rectangles. If it’s too hot where you work with the dough work with 1-2 pieces of dough at a time and keep the rest in the fridge or in the freezer.
4 sheets ready to use puff pastry
Place small puff pastry rectangle short side facing you.
Make long slit cuts with a small sharp knife on the bottom half of the dough (about 6 cuts) leaving both sides intact.Holding gently the top sides of the rectangular fold them over.
Place a spoonful of ricotta cream in the middle.Fold sides of the puff pastry making them slightly overlap.Using your fingers press gently to seal the bottom and center of the pastry.Flip over and place on a baking sheet lines with parchment paper.Repeat the process with the rest of the rectangles.Make sure to leave enough space between sfogliatelle when arranging them on a baking sheet.
Bake in preheated to 355F (180C) oven for 25-30 minutes or until nice golden color.
Let cool and dust with confectioners sugar.
Notes
