Steps
- Preheat the oven to 425°F / 220°C. Unroll 350g of puff pastry and scatter half of 4 handfuls of grated Parmesan over it.
- Fold in half and roll on a lightly floured surface to ⅛in / 3mm thick. Cut into ⅜in / 1cm strips and twist each strip.
- Arrange on a lined baking sheet, sprinkle with the remaining Parmesan, and bake for 12 minutes, until puffed and golden. Cool on a rack.
