Celery Root Soup Recipe

Heat the butter in a large saucepan over medium-high heat. Add the celery root, onion, and garlic and stir to sweat, about 5 minutes; you don't want the vegetables to develop any color. Add the wine and bay leaf and bring the mixture to a simmer. Reduce the mixture until the liquid has almost evaporated, about 10 minutes. Discard the bay leaf and add the cream, milk, and 2 cups of the stock. Return the soup to a simmer and let it reduce and thicken, about 8 minutes.

Carefully transfer the soup to a blender. With one towel-wrapped hand firmly held over the lid, blend the soup until it has completely liquefied. If the soup is too thick, thin it out, 1 tablespoon at a time, with the remaining 1/2 cup stock. Season with salt and pepper to taste. Strain the soup through a fine-mesh sieve.

Pour the soup into small cups and serve warm.
