Garlic Sour Cream Mashed Potatoes

potatoes, cut into 2 inch pieces ((you can peel them but I never do - I love potato skins in my mashed potatoes!))

sour cream ((light is okay, regular will yield richer flavor))

half and half or heavy cream

minced garlic (or 2 teaspoons garlic powder)

butter

salt and pepper to taste ((I use about 1 1/2 teaspoons salt and 1/4 teaspoon black pepper))
