So, I bought some ribs last night. Going to try to do them this afternoon with the 3-2-1 method. First I removed the membrane, split them (too wide to fit in my ECB), slathered them in mustard and added my rub: Smoker was at 260 when they went on. Let's see how they go. Around 3:30PM EST they should be ready for foil. I have a mix of maple and apple chunks for smoke.
