Cut the puff pastry into 4 squares. In the middle of each square place some frozen berries. Gather the corners of the pastry to form little packets, like you can see in the picture. Sprinkle each one with a bit of sugar. Bake in a moderate oven for 20 minutes, until they are golden. Serve with cream or ice-cream.
They took pretty much no time to prepare, weren’t messy and were so delicious. We’ll definitely be having them again!
