Crème fraîche is easy to make. There are recipes in books and online. Mix buttermilk and whipping cream. Some people may use yogurt. Heat the mixture in a double boiler used as a bain-marie. Let the mixture sit partially covered for 8-24 or more hours. The amount of time that the mixture sits determines the thickness of the crème fraîche.
