Creme Fraiche – homemade from one ingredient
This simple method is what comes close to being a Creme Fraiche without using cream. You simply put buttermilk in a coffee filter over a cup and let it drip through. What goes in the cup is the whey and what´s left in the coffee filter is the “Creme Fraiche”.
It takes only about couple of hours to get 1 cup.
Sour cream and Creme Fraiche is not the same thing and I think this method is giving you something closer to being a Creme Fraiche.
