I've had all my smoking experience on my GOSM and Smoke Vault. I'll be starting my UDS build this weekend. I am already anticipating 3 racks of ribs on its first run. I understand the center of the grate will be 35-40 degrees hotter than the outer edges of the grate. If I lay the ribs on the grate, is there a particular figuration that I lay them down? I prefer not to foil (if that helps).
