Potato Rolls

1 package yeast dissolved in 1/2 cup warm water
1 cup milk
1/2 cup shortening
1/2 cup sugar
2 tsp. salt
1 cup mashed potatoes
2 beaten eggs
About 5 cups flour

Dissolve yeast in water.  Measure the milk into a sauce pan and add the shortening.  Heat until milk is scalded.  In a large bowl, combine the milk/shortening, salt, sugar and potatoes.  When mixture has cooled down a bit add the yeast mixture and eggs.  Mix thoroughly with electric mixer.  Add two cups of the flour and mix in.  Set aside the mixture and using a large spoon mix in two more cups flour.  Pour dough onto floured counter top.  Add enough flour to make a dough that you can handle.  Knead for about 10 minutes or until smooth and elastic.  Rub the surface of the dough with shortening, cover and let rise until double in volume.  Punch down dough and then form into rolls.  Cover and let rise again until double in size.  Bake at 375 for 10-15 minutes.
