Why a cup of sour cream doesn't always weigh the same
Volume measurements are forgiving in some ways and brutal in others. A cup of sour cream can vary by 10-20% in weight depending on how it's measured: spooned vs scooped, packed vs loose, sifted vs unsifted. The density figure used here matches the most common published recipe conventions, but if you're after baking precision, weighing on a kitchen scale is more accurate than measuring by volume.
