I'm more apt to just buy whipped cream myself. Though, I'm sure if I ever tasted fresh whipped cream, I would prefer it.
So make it!

There's a big pie-based holiday coming up...get whatever you normally get, but also make up some whipped cream and put it in a bowl. Then people can taste and choose.
My MIL makes fresh whipped cream all the time, and I want to barf it up. I prefer the canned or cool whip, or nothing at all.
You should get her recipe; see what she's doing wrong or different.

I would bet she's not sweetening it up enough.
Oh come on. Are you speaking tongue-in-cheek? I don't know anyone over 5 who doesn't know where beef and milk come from and thinks breaded chicken fingers were cut off a chicken's hand!
Think about when Babe came out, and allllll those kids cried and cried, and went vegetarian for awhile, because they had NO IDEA that their Saturday morning bacon came from pigs. As a longtime vegetarian, I know very well how many omnivores have NO interest in thinking about where their meat came from. I have *one* friend who can talk about the animal the meat came from while preparing, cooking, and/or eating that meat. And think of how many people mean "cow's milk" when they say "milk", when really, the default milk for when humans talk about it shouldn't be a different species' milk.
feel I should add....I'm not an "out there" outspoken veggie, I've just noticed these things over time (or when another veggie friend and I were in anatomy lab talking about thanksgiving when we noticed that our omnivorous friends were nearly throwing up about the convo while we were doing what we were doing in the lab). I don't force conversations on friends, LOL. I've just noticed it.
So anyway, right next to me is the San Francisco Examiner published Prudence Penny binding of the American Woman's Cook Book (if you read that the wrong way boy does it sound bad! binding vs binding). Mine is from 1950, but the copyrights listed in the book go back to 1938.
And it is my go to book for boiling eggs (how long it boils, how long it sits, those things make a difference! hubby does it differently), whipping cream, and other very basic things. I know I learned these things from my mom (who learned it from her mom who gave my mom the Prudence Penny book), but I've forgotten a lot from then for some reason, and I like having the reference.
Wow, it has a recipe for soybean muffins? Never noticed THAT before!
