Homemade Creme Fraiche
I live in a fairly small town which makes getting some ingredients a bit difficult. For example, I have to drive over an hour away from my home to get Creme Fraiche, a French sour cream. Thankfully there’s a simple way to make homemade Creme Fraiche, and you’re just two simple ingredients away from making it yourself. Plan ahead - you’ll need to start the process about 36 hours before it’s ready to use.
Two simple ingredients are all you need to make amazing Creme Fraiche at home. Cultured buttermilk and heavy cream. Use the amounts listed in the recipe below and stir well to combine, then cover the jar with a breathable covering and set aside in an out-of-the-way spot for a 24 hours.
After 24 hours, the mixture should have thickened considerably. Remove the breathable covering and replace with jar lid; refrigerate overnight before using. Keep refrigerated and use within a week.
