I'd wanna try brains but now your article put the scaries in me.
It's not because of poverty. In nature, the alpha wolves eat the organs first. Kidney, heart, and liver are wonderful if you know how to cook them. Fortunately, we still do in Cyprus!
Got to say though, I found no redeeming qualities for the chicken feet I ate in a Chinese restaurant (claws and all), though the Asians who had me try it were really surprised I didn't like them...
Yeah, don't eat brains. I didn't find it rewarding, as I remember, and it's not worth the risk. On the other hand, there was at time when I couldn't resist pickled pig's feet. That time has passed. I won't eat a pig anymore... actually have tried not to eat any animal. But that is difficult to manage, for me, personally.
I always thought it was poverty that led to the consumption of feet, skin and brains, which I think don't have much nutritive value. Kidneys, hearts and livers, on the other hand are quite rich, aren't they?
Sicilians (my mother's heritage) are quite adept at using organ meat, so I grew up with this fare as part of my diet.
