I cooked four ¼-pounders tonight.
I made them with this thing so I know it's the same burger that I usually cook over charcoal.
I put a small handful of pellets in the Bullseye firepot and turned the igniter on. When the pellets flamed, I installed the diffuser and grate and set the controller at 12:00 O'Clock. The temperature went right up to 526° at the grate and 575° on the lid thermometer and held there. There was no visible smoke. I waited a half-hour and took the burgers out of the refrigerator and put them on.
The temperatures dropped because the lid had been opened but quickly climbed back to 472° at the grate and 480° on the lid thermometer. At the 3-minute point I could see grease smoke. I flipped them at four minutes as I do when grilling ¼-pounders over charcoal. They were just barely releasing from the grates.
After four minutes on side two I took them off.
They were done through but were only light brown with weak grill marks. Grill marks aren't very important to me, especially on a hamburger, but I believe that the slight sticking to the grates and the minimal sear and grill marks indicated that more heat and/or more time is required.
Flavor wise...I didn't notice a campfire-like
cooked over a wood fire flavor that I was hoping for. They were good burgers but they need to be better to move me from my current charcoal preference. I'll soon try four more with the controller turned a couple of notches past straight up. I think I want the 700° that charcoal in a Weber kettle produces.
No photographs. Why bother?
