Are you speaking of experience, or just repeating what you read/heard? Because I keep running into that meme, but for all we know it might just be utter BS that’s been so much repeated, and is so hard to invalidate, that people take it as common knowledge.
Not the parent but I know for certain that pig flesh is routinely used as a replacement for human flesh when testing out stuff. Not sure how the physical similarities translate into similarities in taste though.
I do know that in eyewitness accounts of the firebombings of Tokyo during WWII, the smell had been described as roasted pork. Plus human meat is called long pork, so draw your own conclusions.
