Put potatoes in a large pot of water and add salt until it tastes like broth. Bring to a boil and cook until they are tender - about 15 minutes.
Drain water and return to the pot. Cook about 1 minute over low heat to evaporate excess water.
Add sour cream and mash together well.
Season with salt and pepper to taste.
