Riesling soup

4 tablespoons unsalted Butter
1 pound Turnips, peeled and grated
3 medium Leeks, white and light green parts, sliced and washed
1 medium onion, peeled and diced
2 teaspoons kosher Salt
1/4 teaspoon freshly ground black Pepper
2 cups Riesling wine
2 cups beef or chicken broth
1/2cup heavy cream
2 tablespoons minced fresh flat-leaf parsley

1.Melt the Butter in a soup pot; add the Turnips, Leeks, and onion, and season with the Salt and pepper. Cover and cook the vegetables over medium heat until soft and tender, about 20 minutes, stirring occasionally to make sure they do not brown.
2.Add the wine to the vegetables and simmer over medium heat to reduce by about one half. This will take about 10 minutes. In a blender, process the soup to a coarsely-textured puree.
3.Return the soup to the pan, add the broth, and simmer for 3 or 4 minutes. Add the cream and continue to simmer for 3 to 4 minutes more to thicken slightly. Serve the soup in warmed bowls with a sprinkling of Parsley on top.
