Q. I need half
& half. Can I make some with heavy cream and whole milk or skim milk?
A.
It never ceases to amaze us how much math is involved in cooking. You're looking to create something with a fat content of 10% to 12%, up from 3.5% for whole milk and less than 1/2% for skim milk. Heavy cream weighs in at 36% to 40% butterfat. If you use whole milk, mix 3/4 cup of whole milk with 1/4 cup of
heavy cream to approximate half
& half.
The proportions aren't substantially different if you use skim milk because even a small amount of heavy cream adds a lot of fat, but mixing 2/3 cup of skim milk with 1/3 cup of whipping cream will bring you within the right range for half
& half.
If you use other creams with less fat say, light whipping cream, at 30% use more cream and less milk.
If you use light cream, which averages around 20% butterfat, mix
together almost as much cream as milk.
(Now if we can just get someone to check our math. There's never a kid around when you need one….)
