Ok, these are so weird I would have assumed it was a joke. But as a kid, I saw some frighteningly similar dishes, so I thought yeah these might be possible. But by the time I got to 'Potato Fudge', I was so curious I had to look it up. And when I say 'curious', I mean 'Walter-Tango-Foxtrot-curious'. No surprise it turns out it's fake. It's a mockup of this ad: https://retroist.com/potato-fudge-fake/

But now I can't stop thinking about the possibilities of, say, Nutella-Mashed-Potatoes or some such. I mean, it would work. Who's with me...?

Atora suet and suet pudding is still a thing in Knifecrime Island.
