Remove dough from refrigerator and place it on a well floured surface. This dough is very sticky.

Roll the dough into a large circle about a 1/4" thick. Cut with a doughnut cutter.

In a large pot heat shortening to 375°. Fry the donuts until golden brown and drain on paper towels.

When cool, put confectioners' sugar in a paper bag, add a few donuts at a time and shake to coat the donuts.

Enjoy!
