As for what it smells like, Foot was pleasantly surprised, saying, "That actually smells quite nice. Really meaty though. Like a lot richer than pork or chicken." The lab's aroma analysis found similarities to red meat; specifically, pork and lamb. Seeing as smell makes up a huge part of what we taste, this is probably the closest we'll get to figuring out what human meat tastes like, short of nefarious means.
Obviously, going and literally eating yourself or other human flesh is not recommended and will probably get you in trouble with the law. We hope this goes without saying, but don't try this at home, folks.
