Here's how to prep and serve your Vacherin Mont D’Or: Preheat oven to 160C. Cut a garlic clove in half and smear over the top of the Vacherin. Make half a dozen holes into the skin and dribble white wine into the holes. Bake for about 20 mins in the oven or until the top feels soft to the touch and the cheese underneath is oozy. We suggest dipping in hunks of crusty baguette, celery sticks, potato wedges or salami for a sociable starter for 4.
