From my ward cookbook comes this yummy side dish.
3 lb potatoes, peeled and cubed
1 lg head garlic
3 TB cream or canned milk
4 TB butter
1/2 tsp pepper
Salt to taste
Cook potatoes until tender, approximately 20 minutes. While potatoes are cooking, peel the outer skin from the garlic and separate the cloves. Place them in a small saucepan; cover with water and bring to a boil. Lower heat and simmer until garlic is very soft, approximately 15 minutes. Drain and cool. Slip the skins from the garlic and combine garlic with the cream in a food processor. Puree until smooth. Mash the potatoes and add the pureed garlic, butter, pepper, and salt to taste.
