We purchased our LGE in July and are a newbie to the EGG community, and will be doing a turkey for the annual TG conclave.
To prepare, I purchased a cheapie 13# frozen turkey to cook as a test. (Hated to cook my first one for Thanksgiving and screw up)
The turkey test turned great; only I cooked it on the "Vertical Turkey Roaster" and it barely fit in the BGE. The processor left a 1 1/2" neck stub.
I used a plate setter, legs up, without the grate and the neck was visible in the upper metal vent. The bird turned out great (photo attached) internal temp at the thigh was 168 F, in 2hrs and 20 min.
My question; Would the cooking temp. and time change If I used a 1/2 fire ring? I would like to cook a larger bird for the T-Giving holiday,
