For the Love of the Stove

This recipe is courtesy of my Mom.  This was often a side dish we had at holidays, special occasions and always with Easter ham.  It's so delicious and simple you just need to plan ahead.  (The pre-cooked dish spends the night in the refrigerator.)  If you like potatoes, you will love this.
