Instructions

1. Preheat the oven to 200°C.
2. Unroll the pastry and cut it into equal-sized squares.
3. Drop some jam in the middle of each square, spread it out - but not to the edge of the pastry.
4. Roll them up, then place them onto a lined baking sheet. Brush the tops with the egg, if you want them shiny.
5. Bake until golden for 10-15 minutes, then let them cool on a rack.
6. Sprinkle with icing sugar, if you like.
