Asians and in particular Chinese are very practical when it comes to meat. I wouldn’t be surprised if considered fetal swine to be a delicacy. There are probably some great recipes for fetal pork fried rice.
Never eaten a fetus, but I have cooked and eaten whole piglet wrapped in foil, and cooked on top of 12 briquettes in a coffee can...Just like chicken in a can. We did three of them, and they were FINE eating!
