FOR POTATO BUNS:
Roll out dough to a 3/4 to 1" thickness. Cut into bun shapes with a jar, glass, cookie cutter or doughnut cutter, and put on greased cookie sheets about 2 inches apart.
Let rise until puffy but not doubled (they should not be touching).
Brush with milk. Bake at 325 degrees until lightly golden brown about 12 minutes.
