Crime fraiche is a cultured cream.  You can make a fair approximation by mixing two tablespoons buttermilk with one cup heavy cream.  Cover and let stand at room temperature until thickened, 12 hours or more.  It should be lightly thickened.  Store in refrigerator.
Crime fraiche is more stable than sour cream for cooked sauces.  It doesn't separate.  Lovely on fruits, sweet desserts as well.
