1/4 c (1/2 stick) unsalted butter
1 large sweet onion, peeled and thinly sliced
1 large garlic clove, minced
6 large turnips, peeled and diced
7 c water
2 tsp kosher salt
1 tsp pepper
1-1/2 to 2 c whole milk or half-and-half
Applesauce for garnish
In a stockpot over low heat, melt the butter. Add the onions and garlic. Cook until very soft, about 15 minutes. Add the turnips, water, salt and pepper. Bring to a boil, then reduce heat to low and simmer, covered, around 45 minutes or until the turnips are tender. They should break up easily when pressed with the back of a spoon.
Using an immersion blender, puree the soup (or allow to cool and place in a blender to puree, then return to the pot). When smooth, add the milk. Stir constantly for 2 to 3 minutes. Serve warm with a squiggle of applesauce as a garnish.
