Preheat the oven to 375 degrees.

Roll out a quarter of the pie dough to be about 1/8th of an inch thick. Use a 3 inch pastry round to cut out a dozen circles and place on a cookie sheet lined with parchment paper.

Repeat with the other three quarters of dough until you have 48 circles cut out and laid on two lined cookie sheets. Put these pans in the freezer to for about ten minutes.

Take the pans out of the freezer and put a teaspoon of jam in the center of half the rounds and top with another round.

Use the end of a spoon handle to press the edges together.

Whisk the egg and brush over the cookies. Sprinkle with sugar.

Use a fork and poke two sets of holes with the tines into each cookie.

Put both pans into the oven for about 25 minutes or until they turn golden brown and are puffy.

Cool for about 20 minutes and serve.
