Preheat oven to 400º F (200º C)
In a large bowl, mix together the salt with all the spices and breadcrumbs, and then the pork meat.
Add the ground pork, and about ½ cup water. Using your hands, mix all the ingredients together until it has a meatloaf texture, adding water as needed. The sausage should hold together when squeezed, without being too wet.
Unroll the puff pastry on a clean counter, mat or board and roll to make a little larger if desired. Cut into rectangular pieces, depending on the size of the rolls you want to make. You can make small, cocktail size to large sausage rolls. Alternatively, you can make a long roll, and cut into the size desired.Shape some meat into logs, and place close to one end of the pastry, but don’t put too much meat or they will burst open when baking.
Wet one edge of the pastry and fold the other end over the sausage meat. Press down on the edge of the pastry with the tip of fork tines to seal.
Continue to finish all of the sausage meat and puff pastry.
Make 2 or 3 sharp slits on the top of each sausage roll, then place on silicone or parchment lined baking trays.
Brush with slightly beaten egg white, then place into preheated oven and bake for about 25 minutes or until golden brown. Turn trays around and switch levels after 15 minutes for best results and even cooking of the sausage rolls.
Remove from oven and place on cooling rack for a few minutes before serving.
