4 tablespoons butter
2 large turnips, peeled and chopped
1 large onion peeled and chopped
1 large potato, peeled and chopped
1 tablespoon corn flour
1 liter warm chicken stock (vegetable if preferred) (about 4 1/4 cups)
1 bay leaf
Freshly grated nutmeg
Salt and pepper to taste
200 milliliters cream (about 3/4 cup)
1 medium carrot, finely grated
In a large casserole dish, melt butter over a medium heat. Add turnips, onion and potato. Cook, stirring occasionally, for 5 to 7 minutes, until onion is tender and translucent. Using a slotted spoon, remove vegetables from casserole; reserve.
Away from heat, stir flour into casserole juices until smooth. Slowly pour in chicken broth, stirring. Simmer for 3 minutes, until slightly thickened.
Transfer reserved vegetables back into casserole dish; add bay leaf and sprinkle with nutmeg, salt and pepper. Lower heat; simmer for 20 to 30 minutes, until vegetables are soft, stirring occasionally. Remove casserole dish from heat, discard bay leaf and puree soup mixture, a little at a time, in a blender.
Pour puree back into casserole dish; return over low heat. Stir in cream; simmer soup for 4 minutes, until hot. Do not boil. Remove casserole dish from heat; pour soup into 4 individual bowls. Sprinkle each bowl with a little finely grated carrot and serve.
