Fran's Mashed Potatoes

This is how you make perfect mashed potatoes. This is my grandmothers recipe from rural Virginia that mom made all the time.  I never understood why people always complimented these until I tasted how other people make them.  Water?  Really?

5 lbs regular baking potatoes
1 stick butter
1 12 oz can evaporated milk
salt
pepper

Fill large stock pot with water and about 2 tablespoons salt and bring to a boil.  Peel potatoes and cut in half, quarter each half, then place in pot.  Drain when soft and tender, about 30 minutes.

 In a large bowl mash the potatoes with a hand mixer until creamy.  Add butter and milk and beat until smooth.  Add pepper to taste.
