This amazing side dish brings out the natural sweetness of one of winter’s most readily available seasonal vegetables - turnips. Turnips tend to be underappreciated relative to other winter root vegetables. When cooked, they have a sweetness that doesn’t overpower a very mild, radish-like bite. In this preparation, we combine mashed turnips with whole milk and butter, then top them with fried onions to add a little crunchiness to a perfectly textured creamy mash. Serve them with a simple grilled steak or braised short ribs for a rich and hearty winter meal.
