The transformation is magic! Creme Fraiche is like a milder, richer sour cream.
2 c. heavy cream
2 T. buttermilk
Mix cream and buttermilk in bowl
Cover, and let sit at room temperature for 18-24 hours (the warmer the room, the quicker it will develop)
The mixture should reach the consistency of sour cream
When it reaches this stage, cover tightly and store in the refrigerator
for up to 2 weeks.
