Clean the savoy cabbage, cut it up roughly, wash it and cut out the hard stalk. Cut the savoy cabbage into strips. Peel and chop the onions
Heat the oil in a pot. Fry the savoy cabbage and onions for 8-10 minutes. Deglaze with 3/4 l water and cream. Stir in stock, bring to the boil. Simmer for about 10 minutes.
Take out some savoy cabbage strips. Finely mash the remaining savoy cabbage in the stock. Season to taste with salt, pepper and nutmeg. Cut salmon into fine strips. Serve the soup with a dash of crème fraîche, salmon and savoy cabbage strips
A delicious variation: sprinkle raw ham strips over the soup. The soup becomes more piquant with grated horseradish (fresh or from the jar) instead of nutmeg
