Preheat the oven to 390 degrees F (200 degrees C). Take the ready-rolled puff pastry out of the freezer and allow to thaw for 10 minutes on a clean work surface. Line a cookie sheet with parchment paper.Brush the pastry with beaten egg. Scatter the grated cheese over the pastry and season with salt and pepper. Cut into strips of approximately 1/2″-3/4″ (approx. 1-2 cm) by about 6″ (approx. 15 cm). Now twist the ends of the pastry strips in opposite directions to create a spiral effect. Place on the cookie sheet, leaving 1/4″ (1/2 cm) between them and bake for 20 minutes or until golden brown.

Variation tips:

Add your favorite herbs, such as freshly chopped thyme or rosemary.

Try adding dried chili-, onion- or garlic flakes for some more punch.

Add texture and flavor with sesame-, poppy-, caraway or cumin seeds.

Go the sweet route, with sugar & cinnamon or chocolate sprinkles (leaving out the cheese and salt & pepper, obviously)
