So I did my first set of ribs last weekend and the meat and smoke was all awesome except for the underneath was very very tough. Here is what I did, Smoked in a horizontal smoker with hickory wood and lump charcoal using the minion method. Kept around 230* minus a few temp spikes that I controlled quickly they smoked for 2 hours bone down on the grate then I wrapped them in foil with some apple juice for 2 hours bone side to the grate again. I didn't let them go on for the last hour, instead I took them and place them in my fridge overnight for serving the next day. The next day I through them back on the horizontal with just some lump coal to warm them up. Temp around 210* I didn't use enough charcoal. I coated the ribs with BBQ sauce and left them in for 30-45 mins. This was my first attempt at smoking ribs and they taste amazing and I thought they were great except the bottom got to tough. Im guessing I need to flip them upside down at some point but when? In the foil or during the smoke?
