re: First attempt at ribs on my new gmg

Couple thoughts that might have impacted them.

How long did they go for? Did you check the temp with a quick read probe? I think the biggest mistake people make is not letting them go long enough.

Did you wrap them? Wrapping in foil will frick up any bark you had going and prevent the formation of any additional.

Were you drinking beer while they were going? If no, I think you found your problem.
