So, do you call that a full success after all your trial and error? If so, please post up your instructions. I want to give it a shot.
Bruce, dry brine overnight. Pat the chicken dry, put on either Peruvian wet rub or use the Lemon Dry Rub Chuck-O recommended from Susie at Hey Grill Hey. Mount the chicken on the spit, truss. I use the "turbo trusser" but string is fine too. Definitely truss or else you'll dry out your wings and drum sticks. But the really important parts are these:
Cook the chicken on the rotisserie at about 450 to 500 degrees. If you have a thermometer that works for rotisserie (like the Meater, I'm not sure what other kinds of thermometers can stay in and rotate like that) then you want to remember to use it and don't open the lid while the chicken cooks. If you use a thermopen or another kind of thermometer, you'll have to open the lid to check the internal temperature. At 450 or even 500, it will take about one hour to one hour and fifteen minutes to get to an internal temperature between 165 and 170. A little longer if you keep opening the lid.
But do NOT let the grill temperature get below 450. You want to cook between 450 and 500. You will not dry the chicken out, the internal temperature of the chicken slowly rises as it cooks, so you are cooking to an internal chicken temperature of 165. I monitor the middle of the breast with the Meater for done-ness.
After an hour at 450 to 500, with either the Lemon or the Peruvian rub, if your chicken doesn't look like that, I will come to your house and show you how to do it. But I won't need to as long as you cook it at 450 to 500 degrees.
Bruce, I'd love to hear back about your experience.
