Ok, so I bought Jeff's rub and sauce recipes. I have the ribs in the fridge and most of the ingredients for the mac and cheese. I plan to start smoking tomorrow morning around 10 or 11am as we have dinner guests for the ribs and mac and cheese that I'm making.
For the ribs is it ok to put on the mustard and rub tonight and wrap them in saran wrap overnight? Do I need to do anything else with them tomorrow (like add more rub) before they hit the smoker? Also, I plan to smoke with some hickory and peach, does this sound reasonable (~4oz)? I am thinking cutting the racks in half, thick baby backs on bottom, thinner in middle, and mac and cheese on the very top (all at 225 degrees)? Smoking the mac and cheese for 2-3 hours and then removing. Should I refrigerate the mac and cheese after smoking until dinner or keep it warm for ~3-4 hours in a cooler/oven? Should I bother with a meat thermometer in the baby back? I'll add a beer to mini loaf to keep moisture up.
