First cut the vegetables into cubes and the sausages into pieces.
Leave the bacon in a saucepan in the clarified butter. Add the vegetables without the potatoes and sauté. Add the potatoes and stock and simmer until the potatoes are almost cooked. Mash the vegetables with a potato masher to taste. Stir in the cream and let it reduce until the desired consistency is achieved. Season to taste with salt, pepper, thyme and nutmeg. Finally add the chopped sausages and let them heat up briefly.
