Fermentation is an ancient tradition and its methods can be found in almost every culture. Crème fraiche, fermented cream, is the European style of sour cream. It has a robust, tanginess to it that can be interchangeable with heavy whipping cream in savory applications. The buttermilk adds a deep richness to it and the simple preparation makes it a “go to” in your kitchen. Use it in creamed soups and pan sauces, over poultry, seafood and eggs and it makes for a great foundation for dips.
4 cups heavy cream
2 ounces (6 tbsp) buttermilk
Mix all ingredients together and allow to culture at room temperature for 48 hours.
