How much time do you have? That will certainly come into play.
To quote the info packet I have, "turn ins will be about 8:30pm". I'm guessing we'll be able to set up first thing in the morning. So roughly 12 hrs at most.
I need to call the contest organizer and see what else I can learn. It also states there will be 25-30 judges, but doesn't say how many of them your turn in has to feed.
Bob(my boss) and I decided that cooking for turn in only wouldn't be any fun, so we're gonna cook for the guys in the shop and their families and for visitors too. Sounds like a lot of fun, really looking forward to it.
