I cooked two spatchcocked chickens yesterday on my 22.5. My goal was to try two different techniques which would help me try to correct my shortcomings reflected in judges comments re my chicken submitted at last years Alki Beach competition. They liked my flavor, moisture and flesh but did not like my "rubbery" skin.
I basically rubbed them the same but cooked them at a much higher temp. Last year at Alki I did 225 degrees for 4 hours and yesterday I did 325 degrees for one hour and 45 minutes.
My results were about the same. Excellent flesh, good flavor but the skin was not chrispy. I guess I have no recourse but to crisp the skin over a grill for a few minutes immediately prior to serving. That is what I'll try next year.
Yesterday afternoon was cold and windy (32 degrees and perhaps 15 mph wind and snowing most of the time). I used a dry water pan and the top cooking grate. One chimney of Wicked Lump and one chimney of hot K. The WSM performed very well with temp control and fire. I have no problems with that.
As an aside, I've designed a cart for my 22.5 that I intend to build soon and will submit pictures of it when finished.
Looking forward to better BBQ weather. This winter is getting to me.
