I have 4 smoking books that are awesome and helpful. But every one has different cooking times for how long it takes for ribs to cook in smoker. Some say 3 hours vs some saying 4-6 hours at 225-250...I usually keep my smoker between 230-250 for whatever. The first time I cooked ribs it took about 4.5 half hours.I do the 3-2-1 method. Now as you can see in the picture, thats how they turned out. They tasted great, but idk if its suppose to look like that in the middle of rib. I dont know if thats a good sign or not good sign Someone said that their called smoke rings and thats good???. I have Pork baby back ribs sitting in fridge with dry rub for a cook tomorrow. So any input or help would be greatly appreciated d.
