Granny's Creamy Mash Potatoes
As soon as the potatoes are tender, drain them in a colander. Place a food mill fitted with a small disc/blade over a glass bowl. Process the potatoes through the food mill, turning the handle back and forth to force the potatoes through the disc. As soon as the potatoes are mashed, slowly whisk in enough of the half and half/butter mixture to make the potatoes very creamy.
