I keep seeing that people measure by weight,  I get that for the chocolate.  But are all of you also weighing the cream, or do you do this by volume (i.e., measuring in a liquid measuring cup)?

I am unclear if you are just measuring out 8 ounces in a "wet" measuring cup, or if you are measuring out 8 oz on a scale.

In a glass measuring cup like Pyrex. Not one that ypu wpuld measure flour in.

chocolate by dry ounce, cream by liquid ounce. So the chocolate on a scale, the cream in a measuring cup.

I was a little confused about it too.  Thanks for the clarifications!

I sure am glad I was figuring it correctly.

Thank you! This is exactly the info I needed as I had 8 oz of cream on the scale and it weights 4 oz, I thought....I'd better check on this.  Donna

8oz of cream (or any liquid) in a measuring cup should equal 8oz by weight.

Very weird that your 4oz equals 8oz.

The weight of a liquid depends on its density - so 8 fluid oz of water equals 8 oz on a weighing scale because the density of water is 1 gram per cubic centimetre (yes I'm Australian so that's metric - 250ml equals 250g for this cup of water).

Cream has a very similar density to water, so it will weigh nearly the same as it measures in a liquid measuring cup - so I weigh my cream for ganache.

Oil on the other hand has a different density so it will weigh in grams or ounces a different amount to its measurement in millilitres or fluid oz or whatever.

there is no way your cup of cream can weigh 4 oz unless you've whipped it first and incorporated air to lower its density!
