What (roughly) does horse meat taste like?  What kind of dishes can I make with it? 
Back in the late '90s, biologist Joe Staton did a comparative study of the tastes of different animals for the Annals of Improbable Research.  His hypothesis was that the relatedness of tastes of animals is correlated to their evolutionary ancestry.  You can read an abridged version of his article here.  Looking at the phylogenic tree at the bottom of the article, horse meat has the general flavor of beef and is most closely related to deer (venison) and American buffalo (bison).  In my experience, horse meat is like a cross between venison and beef.  Edit: In case anyone was wondering, human apparently tastes like pork.
