A portion of the beaten egg should be set aside for the egg wash, and the spinach combination that has been allowed to cool should be combined with ricotta, feta, cream cheese, and the beaten egg in a large bowl.
Mix well until everything is incorporated.
3. PLACE THE PASTRY IN PLACE:
The puff pastry should be rolled out into a broad rectangle with a thickness of approximately one quarter of an inch on a surface that has been gently dusted with flour. In order to make the sheets more equal, you may just need to give them a tiny roll if you are using pre-rolled sheets.
4. RELECT THE PASTRY TOGETHER:
After spreading the spinach filling over the puff pastry in an equal layer, leave a tiny border around the borders of the dough.
Using the long edge as a starting point, roll the dough up like a jelly roll, then squeeze the edges together to bring them together. Making a huge pocket out of the pastry may also be accomplished by folding the crust over the filling and then sealing the edges.
