Mashed Potatoes

3 pounds of All Purpose Potatoes
1 stick of Butter
1/2 c. Milk
salt and pepper to taste
1/4 c. Sour Cream, optional

Wash, peel and dice the potatoes, place into a large pot of water. Boil until tender and start to break apart with a fork when touched. Drain the water off, and return the potatoes to the pan. Add the butter, salt and pepper, and using either your mixer or a masher, mash the potatoes till they no longer have large lumps. Add milk a little at a time, until potatoes are at desired texture and thickness. Add sour cream if desired, you can even eliminate the milk and use the sour cream instead if you so choose.
