Cut the sheets of puff pastry in half.*
Place the cut puff pastry on a flat floured surface. Brush with the melted butter. Do not use excessive butter, just enough to brush over the surface. This adds to the savoriness of this dish. You can eliminate this if you wish.
Brush the egg wash over the edges of the puff pastry.
Place one of the sausage rolls on one side of the puff pastry sheet.**
Fold over the sheet onto the meat sausage shape and seal well.
You can use a knife to cut the edges neat and square, then a fork to finally seal the roll.
On a parchment covered cookie sheet, place the sausage rolls.
Place the egg and water in a small bowl and whisk well. Use this for the egg wash.
Use the egg wash and brush the tops of each roll.***
Preheat the oven to 375 degrees F. Bake the sausage rolls ~30-40 minutes until the sausage is fully cooked and the psatry is nicely browned. The interior should be > 150 degrees F.
Remove from the oven and cool enough to handle, then slice into pieces (see picture), or you can leave them whole and serve them as a main course. Or serve them as half moons, see above.
They are much better warmed, but can be served at room temperature if fresh.
