6 potatoes, peeled and cubed
2 onions, chopped
1/2 cup unsalted butter
1 teaspoon salt
1 teaspoon ground black pepper
1/2 cup dry milk
salt and pepper to taste
1/2 cup chicken broth
Rinse potatoes and rinse under cold water. Place in a large, nonporous pot, far enough from the heat source to maintain a few inches of water above the surface.
In a large dish or bowl combine potatoes, onions, butter, salt, pepper, milk and broth. Cover and simmer until potatoes are tender, 1 to 2 hours. Season with salt and pepper.
