Dr. Mac, we're gonna make you famous at that party.
Get some O them Hog Drippin's and add them to the beans.
Beans done in a Smoker are the best you can have. The Smoke will give it a flavor like they've never had. If they don't like it you can give them their money back
Here's how I prepare, in the recipe archive. There are also other bean recipes there, you might try a search:
Smokin Okies Smoked BBQ BeansI've also done variations with fresh, rehydrated beans, but the family likes these better.
If you need to make a BUNCH Of them, guess you can make them in those aluminum pans, add some chopped brisket/pulled pork, put the covers on them and hold them in your oven at home until ready. You could turn out quite a few this way.
Another variation is AAHH's method, do these we're you're cooking something else in the smoker.
