Crème Fraîche is a thick, creamy dairy product originating from France. It is made by fermenting heavy cream with specific bacterial cultures, which gives it a slightly tangy flavor and a smooth texture. Crème fraîche typically contains around 30% fat, making it richer than sour cream. This versatile ingredient can be used in both sweet and savory dishes. It can be dolloped on soups, stirred into sauces, or used as a topping for desserts like fruit tarts. Unlike sour cream, crème fraîche can be heated without curdling, making it a popular choice in cooking.
