Mine is duck

At first glance I thought you actually did.
If we're choosing this by animal, then I would probably have to choose Pork.
I love Bacon and Gammon, Chops, Crackling, Belly Pork, Pulled Pork (which I had for the first time yesterday) and Sausages.
I like other meats too, but there's so many lovely flavours that come from Pork. I'm very glad I'm not Muslim or Jewish.
