I did some hot and fast St. Louis Style the other night. Lots of rub on them and 2 hours at 275. I then wrapped them tight in foil after adding some brown sugar, maple syrup and apple juice and let them go for another 1 1/2 hours at 270. Did not need any sauce for them as they turned out great. Nice smoky pork flavor with a sweet and little heat (due to the cayenne in the rub) at the end.
