No need to boil. Dry rub lightly, set to 225 and let it go 3-4hrs. When the meat start to pull back from the bones, you can sauce them for 10-15 min if you like. The goal is not "fall off the bone" meat, you should be able to take a solid bite of meat. They shouldn't fall apart when you cut them. If you are in a rush, you can wrap in foil after 2.5hr for 45min to an hour. This will finish the cook quicker. Leave the lid down for at least the first 2hrs. If you like a sweeter rib, cover them in brown sugar and butter when you wrap them in foil. Anymore, I don't wrap, just leave them meat side up for ~4hr then sauce just before removing.
