Zaansemosterdsoep (Dutch Mustard Soup)

This wonderful (but simple!) Dutch soup is traditionally made with mustard from the Zaan. Any mustard with whole mustard seeds will work well too.

125 ml (1/2 cup) creme fraiche

 Bring water to boil. Add creme fraiche, mustard and cheese; whip until smooth. Add cornstarch. When the soup thickens, add salt and pepper to taste. Garnish with onion. Serve with bacon bits on the side.
