I don’t have it handy right now, but there is a little chart out on the internet somewhere that gives all the incantations and combinations for making such-and-such dairy product from this-and-that other dairy products - like what ratio of, say light/single cream and whole milk to make half-and-half, and what combination of heavy cream and 2% to make a light/single cream substitute.
It’s actually quite a handy little thing to have, but most days, I just guess.
And that’s good information on “cereal cream,” I never knew that. Thanks for that.
