Sincere apologies.... It should say, BRAISE, not brine. Sorry for the misspeak. I can certainly understand where the confusion is.
For he braise liquid, I use equal parts of Jeff's sauce and apple juice. If you really like them sweet, you can add a half part of honey. I smoke my CSRs directly on the grate for about 3 hours and then put them in a foil pan. I add enough braise liquid to get to about half way up the ribs and then cover with foil. I let them braise for about an hour and they are usually really enjoyed by all. I'm running all of this at 250-275*.
I wanted to give you a more detailed recipe. I hope it helps and I hope you have good luck with your CSR's. Let me know how they come out. Joe
