Preheat oven to 400 degrees.

On a clean, lightly floured surface, unfold 1 sheet of the pastry. With a pizza wheel, kitchen scissors or sharp knife, cut vertically into 3 equal pieces and slice each in half horizontally. Then slice each square on a diagonal to make into triangles. Repeat with the second pastry sheet. You should have 24 triangles.

Mix jam and lemon extract together. Thinly spread each triangle with 1 teaspoon of jam.

Roll up each triangle snugly from the wide base to the tip at the top. Place on the baking sheet.

Brush them with the egg wash then use your finger to shape them slightly into crescents, keeping the tip tucked underneath.

Bake for 15-20 minutes, until golden brown. Allow to cool to room temperature then dust with confectioner's sugar.

Store in an air tight container until ready to serve.
