I am having some friends over for some BBQ tomorrow and thought I'd smoke some pork ribs (St. Louis style) and have a few questions before I smoke them: 1. I have to probably smoke them the night before for I have to work the day of and probably don't have time to do them then, is this a fools errand or will they still be good doing the night before than warming up on the grill with some sauce? Thoughts? 2. Do you always need to foil ribs and if so when? How can you preserve the crispy bark you worked on developing? Also do you always pull at finishing temperature or can you let them go longer if for example the ribs still seemed a little tough? Thoughts? BTW I own a Masterbuilt Double Door Propane Smoker (below) Thanks in Advance!
