Great photos! Does anyone have the Baby Back by Fast Eddy's Way they could share? The pictures of those ribs look awesome! I am planning to do some ribs this afternoon and would love to try that method.
I've done that cook over and over with large racks of baby backs and there's been almost zero deviation in the results and it's so simple.
275* is the setting start to finish, no foil just place them on zone 4 let your PG 500 work it's magic. For me, using large racks of baby backs packed by Smithfield are ready at the 4:15 mark every time and I sauce them then 6-8 more minutes so the sauce takes a set. I would say a properly trimmed Saint Louis style rack would be right on the money in that time frame as well.
It's gotten to the point where I don't even check them anymore after doing a dozen rounds or so of them, in they go at 275* and I don't open the lid until 4:15 minutes later they are fantastic every time with the only exception being a few smaller racks that I pulled at 3:45 minutes and let the warming drawer do it's thing while the larger ones finished.
