What exactly is creme fraiche?
Crème fraîche, French for “fresh cream” and anglicized simply as creme fraiche, is a thick cultured cream. Cultured cream is cream soured with a bacterial culture, similar to sour cream or Mexican crema. Creme fraiche has a nutty, tangy, slightly sour flavor and a fat content of around 30 percent.
Crème Crue de Normandie or Crème Crue Fermière or Crème Fraîche Fèrmiere: Unpasteurized cream to which no bacteria cultures have been added and which has never been heated.
