Haggis is delicious.
Pork products, as a general rule, are not. The exceptions are: pepperoni/salami/other spiced type things like that, smoked sausage, frankenfurters and some sausage rolls (just not the cold ones where the meat tastes like Play Doh). Bacon, ham, gammon, normal sausages etc. make my stomach turn!
(Basically I only like overly tampered with pork)
