How to measure Sour cream by volume
- Spoon into a dry measuring cup, pressing gently to avoid trapped pockets, and level.
- Crème fraîche measures nearly identically if you are substituting.
Why the weight varies
Full-fat and light sour cream differ slightly; a level cup of full-fat sour cream is dependable.
Sour cream’s job in bakes is acid plus fat plus moisture, and pound cakes and cheesecakes are sensitive to all three. It is also a common cups-to-grams lookup because European recipes phrase it in grams of crème fraîche.
Which value we publish, and why
We publish 230 g per US cup of cultured sour cream (USDA FoodData Central); King Arthur rounds it to 227 g (8 oz).
