Bring large pot of water to a boil. Peel and quarter potatoes, add to the boiling water. Boil the potatoes until fork tender.

Drain the potatoes then transfer to a large bowl. While still hot add the 6 Tablespoons of butter, cream, sour cream, and ¼ teaspoon of salt to start. Using a potato masher or electric mixer, mash or whip the potatoes until the butter has melted and is mixed in.

Add more salt, butter, or cream to taste and preference.
