Step 1

In a large pot, cover potatoes and garlic with water by 1 inch. Bring to a boil, add salt and simmer until tender, about 15 minutes. Drain well.

Step 2

Put the potatoes and garlic back in the pot and cook over low heat to evaporate the rest of the water. Mash in the butter with a potato masher. Add the heavy cream in stages until the desired consistency reached. Season with salt and pepper.
