About sour cream measurements
Full-fat sour cream is thick but only a little denser than water, about 1.04 g/ml or 245 g a cup. Light and fat-free versions are bulked with thickeners and stirred-in air, so they spoon up lighter — pressing it firmly into the cup is the only way to get a repeatable weight.
