Where have these been all my life?? I've seen several posts on CSR's so I had to give it a go, so I grabbed a pack on Thursday, did a bit of research and they look like they're from the loin. I've been on a fruit rub kick lately (Thanks Eric) and decided to give his Blueberry-Cherry Rub a try. Started off by dehydrating some frozen blueberries and red bell peppers in my Big Chief. This took a while. Once they were dry it was time to grind them down and mix the rub. Once the rub was ready, I took the CSRs out of the fridge, rinsed off, splashed some apple cider vinigar on them and applied the rub. Set in the fridge while WSM heated up. Put CSRs in WSM at 220*F and smoked with apple until 140F* IT. At 140*F, I mixed up a blueberry/butter mix and brushed the CSRs and smoked until done at 150*F IT. I didn't want to hide the dry rub on these, so they were left unsauced. Turns out they didn't need any sauce, these were tender, juicy and downright delicious. Will be doing these again. This rub is amazing also. If you have a dehydrator and a coffee grinder and haven't tried this rub, I highly recommend it, it's a nice change of pace from the sugar based rubs. Thanks for looking Dried tart cherry after grinding Blueberry dust! Rub all mixed Rub applied and started turning blue when it got wet, was kind of fun to watch. Smoke time 140*F IT before blueberry-butter mix Blueberry butter melted quick Done!
