1 In a large, heavy, thick-bottomed pot, pour in the 1st cup of broth and bring to a boil. Add the onions and cook until translucent but not browned, about 5 minutes. Add the sliced turnips and potatoes and stir to coat with the broth. Add 2 teaspoons of salt, cover and reduce the heat to low. Cook, stirring occasionally, until the turnips and potatoes are tender, about 20 minutes. 2 Add the rest of the broth and increase the heat to bring to a simmer. Cover partially and cook over medium heat until the turnips and potatoes are very tender, about 10 minutes. 3 Scoop out about 1/3 of the potato and turnip solids with a slotted spoon and reserve. Using a submersible blender purée the rest of the soup until smooth and creamy. Add the potato/turnip solids back to the soup and stir. Season with salt and freshly grated nutmeg. Ladle the soup into shallow bowls and garnish with the parsley before serving.
