This is a great, basic way to serve turnips as a sweet side dish that can balance their mild bitterness. 

2 lbs turnips, peeled and cut into wedges
salt to taste
2-4 tablespoons butter
sweetener of your choice, like maple syrup, honey, etc. (about 1/3 cup or to taste)

In a skillet, combine turnips and salt with enough water to barely cover.  Bring to a boil, and then simmer until turnips are just tender, about 10 minutes or less.  Drain, remove turnips and dry the skillet.  Reheat skillet on high, add butter and sweetener and boil until mixture has turned amber colored, about 2 minutes.  Add turnips and cook until well coated with the sweet glaze, about 5 minutes.  Make sure to stir frequently to prevent sticking.  Serve hot.
