Boursin cheese is a white creamy cheese with a smooth taste. It's similar to cream cheese, but a bit more crumbly like goat cheese. While you might think the word "gournay" is a play on the word "gourmet", it is not. "Gournay" is actually a town in Normandy France which is where this cheese originated. This cheese spread tastes fantastic spread on crackers or celery but it also adds a deep flavor and creaminess to the mushroom sauce.
