I will spatchcocking a kosher turkey. After spatchcocking it, I will rub it with some kosher salt, baking powder, and a personal poultry rub. It will then dry brine in the frig overnight. My question is : At what temperature should I cook it? I have seen recommendations from 350 to 450 Fahrenheit. I am not worrying about time because I will monitor doneness with a dual temperature probe (gRill 2)
