Crème fraîche is similar to sour cream. While sour cream and crème fraîche are both used to add richness and tangy flavor, they are not the same thing. And is it worth taking the extra time to make your own crème fraîche? I’m going to say absolutely, yes, depending on the use.

Use it anywhere you would use sour cream. Because sour cream has less fat but more protein, simmering or boiling it will result in curdling. Crème fraîche is a better choice for sauces or soups.

Crème Fraîche

In France, crème fraîche was traditionally made from unpasteurized cream that naturally contained the right bacteria to thicken it. Since our cream is pasteurized here in the US, this crème fraîche is made by adding a fermenting agent with bacteria to heavy cream.

  • 2 cups heavy cream
  • 3 tablespoons cultured buttermilk


  • In a glass jar, combine the buttermilk with the heavy cream.
  • Cover the jar tightly with cheesecloth or other breathable material. Let sit at room temperature (70 to 75 degrees) for 24 hours.
  • Remove cloth, stir. It will be thick but will get thicker. Screw on a lid, and refrigerate for another 24 hours before using.
