I've catered a few large party's, BBQ always, and I've been told these are the best baked beans and they are super easy to make
first thing I cook up a pound of bacon, then I'll dice a half a white onion and sauté it in bacon grease, drain and set aside, then I use a gallon of pork & beans and pour it in a baking dish, I use baking stones/pans, chop the bacon and add it and the onion, put in a handful or so of brown sugar and about a 1/3 of a 8oz jar of molasses and about a tbls of regular old yellow mustard stir it up good and put it in the oven on 350 deg.stir it once in a while as the brown sugar melts for a 1/2 hr to 45 min depending how thick you want it
as you can tell I don't measure much hell I ain't making a cake here just taste it and add a little more of whatever you think it needs, I can tell by the color if it's right
try this I promise you won't be disappointed , bub
