Preheat oven to 200 degrees C. Grease a baking tray or line with baking paper.
Unroll puff pastry sheets on a dry, lightly floured surface. Sheets should be about 1/2 cm thick. Spread sugar liberally over the entire surface of each sheet. Tightly roll or fold up the pastry from each side of the sheet to meet in the middle. It will look like face to face snails. Slice the roll into 1 cm slices, like a loaf of bread. Lay out on prepared baking tray about 2 cm apart. Bake in preheated oven for 10 to 15 minutes, until golden brown.
