When the pastry is at room temperature roll it out.
Using the rolling pin, flatten the pastry even more to around 5mm thick.
Cover the surface of the pastry with a sprinkling of demorara sugar.
With the rolling pin, gently push the sugar into the plaster by gliding the rolling pin over the pastry again.
Fold in the two edges to the centre line so it looks like a leaflet.
Repeat the above steps twice by flattening the pastry, add more sugar and push into the surface, then fold to the centre line again. This should be done until you have folded the pastry over three times in total.
Roll in the edges to the centre line, creating two tubes which resemble a heart shape.
Cut into 4cm slices and place on the baking tray.
Lightly sprinkle a bit more sugar over the top of the pastries and place in the oven at 180℃ for around 15 minutes. It may take less time than this so keep a close eye on them to make sure they do not burn.
Surve warm and enjoy, or store in an airtight container and consume within 3-4 days.
