Preheat Your Oven: Start by heating your oven to 180°C (356°F). This ensures that the oven reaches the right temperature for baking, which is crucial for achieving that perfect golden puff in your pastry.

Prepare the Puff Pastry: On a lightly floured surface, roll out the puff pastry dough into a rectangle or your desired shape. This is the base of your snack, and a thinner roll will yield a crispier texture in the final product.

Mix the Filling: In a separate bowl, combine the cottage cheese and egg until well blended. The egg helps bind the cottage cheese, giving it a smoother consistency that will be easier to spread.

Assemble: Spread the cottage cheese mixture over the rolled-out dough, leaving a small border around the edges to prevent the filling from oozing out. Then, carefully roll up the puff pastry into a log, starting from one of the longer sides. Ensure the edges are sealed by pressing them lightly with your fingers.

Slice and Bake: Cut the log into 1-inch thick slices. This size is ideal for a bite-sized snack that’s easy to handle. Place the slices on a baking tray lined with parchment paper. Remember to space them out since the dough will expand as it bakes.

Bake to Perfection: Place the tray in the preheated oven and bake for about 25 minutes, or until the puff pastry is golden brown and has puffed up beautifully.

Cool and Serve: Remove the tray from the oven and allow the pastries to cool slightly on a rack before serving. This resting period helps the pastry set, making it easier to serve and eat.
