We completed the trial run yesterday. Things did not go according to plan. As much as I wanted to use the smoker for the burger, logistically I thought it would be easier to do it on-sight in the oven. There was just one problem. When I checked to see if the pan would fit in the oven, I didn't slide it in all the way. When I saw the width was good, I assumed the rest of the pan would fit. I was wrong, the oven door would not close. I was not there when the error of my ways was discovered. Fortunately, my wife was able to call the pizza place and they were willing to cook the burger for us. This really saved the day.
I learned a lot, but there were still some unanswered questions. The biggest one is how long will it take to cook in an oven or a smoker, rather than a 550° pizza oven. Also, I realized all my elaborate plans on how to flip the burger and buns went out the windows. Using a peel at the pizza place made life much easier.
With someone else cooking the burger, I had no control of the cooking time. The restaurant got slammed with a brunch crowd before I got there, so I have no complaints. I was very grateful for their help. It was a little over cooked for my liking, but not bad. It was very juicy. There were some pieces with a little pink in the middle. Nobody complained. It tasted great. I really liked the seasoning salt we used. The local grocery store is known for their various rubs and spice blends. They did not disappoint.
All in all it was a good day. I was able to get 36 servings from the burger, which weighed 18.2 pounds fully assembled. I think we had 32 people, so it worked out well.
Here is a video of the assembly. More pictures to follow.
