Crème Fraiche vs. Sour Cream: An Overview

The fat composition of sour cream is nearly 20%. You have to mix the cream with a culture of lactic acid; it will then acquire a sour taste. Sometimes stabilizers are added to thicken the cream. The mixture might curdle if you apply heat or simmer it since it contains more protein than fat.

Crème fraiche contains 30% fat, and traditionally it is unpasteurized. As a result, it is already rich in bacteria needed to make it thick. In some countries (for example, the United States), pasteurization is mandatory for health concerns. In this case, crème fraiche is made by adding fermenting agents with necessary bacteria.

Sour cream is less thick and has lower fat content compared to crème fraiche. But crème fraiche is tangier than sour cream. It won’t curdle, and you can easily use it in sauces and also soups!
