For the Christmas ravioli, prepare the short pastry as described in the basic recipe.
Preheat the oven to 170 ºC hot air.
Roll out the dough on a floured work surface and cut out ravioli-like squares with a cookie cutter.
Place a dab of jam on half of the cookies and cover with a second cookie. Press down gently all around. The jam will create a nice ravioli curvature.
Arrange the cookies on a baking sheet lined with baking paper and bake for about 12 minutes.
Then sprinkle the finished Christmas ravioli with powdered sugar.
