Cheese – How to convert volume to weight for soft cheeses like ricotta and mascarpone

cheeseMeasurements

Ricotta and mascarpone are messy to measure in measuring cups, so I'd rather use a scale. How much does one cup of each weigh?

Best Answer

I don't have mascarpone to check, but the Internet says that there are on average 225 grams per cup. Mascarpone being mainly a mix of water (density 1 g/cm^3) and fat (density 0.9 g/cm^3), this sounds about right.

I don't think it is possible to give a reliable conversion for ricotta. First, many countries don't have normal ricotta, so people use all kinds of substitutions, frequently not being aware that they are not the same thing. So it is possible that whatever you can buy in your supermarket under the name "ricotta" is not the same thing as whatever the recipe author can buy. Second, real ricotta is made from whey, and the amount of whey left in the cheese varies, so you will have a different amount of water between brands, which will change the density.

With this difference, I guess you could just assume that ricotta has the density of 1, measure out 235 grams and call it good enough. This will usually be a different amount from what the recipe author uses - but then, so will be measuring out a cup by volume.
