I don't have a fixed recipe for chili con carne, except that it contain chilis and meat. I make a lot of my own chili powder, and tend toward the 300 year old methods of northern Mexico (which Texas and NM used to be).
I do have and have posted my recipe for BBQ'ed wooly mammoth, including amounts for BBQ beans, slaw, and potato salad. Serves about 1500. I posted that on a thread about the Japanese bringing back the wooly mammoth. ;)
