On a lightly floured surface, unfold the thawed puff pastry sheet. If necessary, use a rolling pin to flatten and smooth the pastry.
Cut the pastry into 12 equal strips. Coil each strip, wrapping loosely, into a circle or spiral. Moisten the outside end of each strip with a little water and secure it to the pastry to prevent pastry from uncoiling during baking. Place pastries on an ungreased baking sheet.
Bake in a 400 degree F oven about 15 minutes or until golden. Cool on a wire rack. To serve, in a small saucepan heat preserves until melted, stirring often; drizzle over baked pastries. Let the preserves cool slightly. Top with whipped topping. Sprinkle pastries with chopped nuts. Serve immediately. Makes 12 Danish.
