6 med. potatoes, unpeeled
3 tbsp. butter
2 med. onions
2 bay leaves
1/2 tsp. white pepper
2 c. yogurt (room temperature)
4 tbsp. minced chives

Steam potatoes whole until tender. Saute onions and bay leaves in butter, sprinkle with pepper. Cover and cook over low heat for 1/2 hour. Remove skins from potatoes.

In the blender puree the potatoes with the onions, removing bay leaves first. Return to the saucepan and whish in the yogurt. Simmer over low heat for 15 minutes, stirring occasionally. Garnish with fresh chives.
