Puff Pastry Sausage Rolls

1. Preheat the oven to 400 degrees F (200 degrees C). Line a baking sheet with parchment paper.

2. Unroll puff pastry on a lightly floured work surface, and cut each sheet into 4 pieces. Place 1 sausage into the center of 4 of the pieces of pastry. Lay the remaining 4 pastry pieces over the sausage and press the edges of the pastry together to seal tightly. Slash the top of each pastry several times with a sharp knife.

3. Whisk egg and water together in a small bowl, and brush egg wash over the pastries with a pastry brush. Place on the prepared baking sheet.

4. Bake in the preheated oven until deeply golden and puffed, about 20 minutes.
