Place the ribs bone side down if possible.
Let the ribs cook at about 240°F and with smoke for 2 hours.
At the end of 2 hours, wrap the ribs with foil.
Do this carefully so as to not tear the foil. If you do happen to tear it, just double wrap it with another piece.
Place the wrapped ribs back into the 240°F smoker and you can even stack them all together if you need to.
Let them cook in this wrapped state for about 2 hours.
With a total of 4 hours past, you now want to unwrap them again.
They will be very soft on the outside and very tender on the inside, and this last step is to firm up the outside just a little before serving them.
Remove the foil and place them back into the 240°F smoker for 1 hour.
Alternative for Step 3
Throw them on a very hot grill and let the high heat give them a good char. Paint on some barbecue sauce if you like sticky ribs.
