How to Make It
Wrap the thyme, bay leaves, peppercorns and cloves in a piece of cheesecloth and secure with kitchen string. Put the bundle in a large saucepan and add the root vegetables, onion, garlic and white wine. Add enough water to cover by 1 inch and bring the mixture to a boil over high heat. Reduce the heat to moderately low and simmer until the vegetables are tender, about 45 minutes. Drain the vegetables and discard the herb bundle.
Return the vegetables to the saucepan and cook over high heat, stirring, until the vegetables are dry, about 3 minutes. Remove from the heat and smash the vegetables with a potato masher. Stir in the butter and maple syrup and season with salt and pepper. Serve hot.
