I've decided to make my own creme fraiche. I used a small amount of ingredients for my first time to see how it turns out. Late last night I got the wild hair to go for it.
I used just short of 1 cup of heavy whipping cream and 1 1/2 tablespoons of buttermilk. I combined them in a clear glass jar and left it on the counter with out a lid. It's supposed to develope into a thick consistancy within 12 to 24 hours. The thicker and creamier you want it the longer you're to keep it out.
When I woke up this morning this is what it looked like.
