I love the way Salmon cooks on the BGE. I have tried various ways and cooking it on a cast iron semi circular griddle seems the best way for us. I cook it at 225-250 grid temperature indirect. I put on some Mrs Dash lemon Pepper seasoning, some salt, and some turbinado sugar. Today I used some cherry wood. Pulled it at about 140 degrees and it was perfect.
I had the camera ready this time. Here it is when it went on. An hour later it was done but I didn't take another picture since it doesn't change very much.
