Yes. Part of the final time (the 3rd number when cooking ribs 'by the number') is to reset the bark and/or to glaze a sauce if you use it. On this rack of BB ribs, I wrapped about an hour, then flipped them meat up, and just made a boat with the foil. This is maybe 20 minutes after the flip, and the bark has re-set. I'm not a sauce guy, but now would be a good time to add sauce and let it glaze for 5 or 10 minutes.Nope, is meat side down preferred method?
Will have a go at that way next time if it is.
