6 carrots, peeled and chopped
4 large parsnips, peeled and chopped
2 turnips, peeled and chopped
½ cup butter
½ cup heavy whipping cream
¼ teaspoon ground nutmeg
1 pinch cayenne pepper
salt and ground black pepper to taste
Place carrots, parsnips, and turnips into a pot and cover with cold, lightly salted water. Bring to a boil and cook until a fork easily breaks apart the vegetables, about 25 minutes; drain. Return vegetables to the pot.
Mix butter, cream, nutmeg, cayenne pepper, salt, and black pepper into vegetables; roughly mash together with a potato masher until vegetables are broken down but individual colors are still visible.
