Mincemeat pie with actual meat wasn’t a fad, it was a treat for decades! It was made with venison and was quite good .
And who doesn’t like lime jello with cottage cheese or Snow Pudding? Actually Snow Pudding has been around as long as venison pie, maybe longer, and the original snow pudding and it’s also quite good.

The mincemeat pie routine in State Fair is really funny as the mom and dad sneak back into the kitchen to put more and more brandy into the pie. But they made a winner!
Grandma’s mincemeat pie was, as you say, made with venison, and definitely not a fad. It was regular fare on the farm.
Who doesn’t lime lime Jello with cottage cheese? Me! Anything with cottage cheese is gag-worthy food for me. I wish I could like it, and I try. Can’t do it.
