Gruyere Cheese Straws

We had a small quantity of puff pastry, about a third of a rolled sheet, sitting in the fridge, so I rolled it out thinly, covered it with grated Gruyere and quite a bit of cayenne pepper, then folded it in half and rolled it out agai.  I then cut strips, twisted them into little corkscrews, and baked at about 180C for 10-12 minutes, until crisp and cheesy.  Delicious with the cocktails.
