The smart thing to do is go with the advice already given. Parties aren't the best place to experiment.
Personally, I go against that advice. LOL! Cookouts and informal "parties" are where I experiment. Again, I wouldn't advise it but I'm not in the business of selling bbq and don't plan on going into it so it's no biggie to me. I figure I serve enough different type of foods that if they don't like what I've tried there's something else there they'll like.
