How to measure sour cream

Sour cream won't pour on its own — spoon it into the cup and level the top.

Because a cup measures volume rather than weight, the most reliable way to measure sour cream is with a digital kitchen scale. If you are working from cups, keep your technique consistent every time so your results are repeatable. For more, see our guide on baking by weight versus volume.

Sour cream conversions: FAQ

Why doesn't a cup of sour cream weigh the same as a cup of water?

A cup measures volume, not weight. Sour cream is denser than water (240 g versus 237 g per cup), so the same volume has a different weight. Weighing in grams is the most accurate way to measure it.
