So i've cooking shatloads of pork spares but always flat on the smoker. I have lately been smoking for more than normal amount of people so I got a rib rack. Please tell me the time increase, concerns, tips or anything about using the rack. I have used it twice and my results have varied greatly from normal. Granted I have had pouring rain but I cook under a pop up canvas so it's not pouring onto the smoker. The smoker does get some drops splashed on it when it's really coming down tho. Anyway, I always cook till I get a certain bend from the ribs and they are always great. The first rib rack cook I did I had three spares on. One got done at 7 hour, and the other two at 9 hours. WTH! I spritz every 30 minutes after bark is formed. I stopped towards the end, for the love of Mike, just to get these SOBs done. They weren't horribly dry, and they were still really good but is being close together really increasing cook time that much? Cook 2 I did 2 baby backs and 1 spare. I spritzed them in 30 minute intervals again but stopped 4 hours in because i could tell they were going slow again. They were all bend test approved at the 6 hour mark and I removed. The baby backs suffered some dryness.... Spares were good. Ultimately, is this long cook time rib rack related? My Spares usually done in 5 hours and babies even less.
