Searched for spatchcock turkey and read several posts about it. Looks like this is what I'll be doing this week. I am at my folks' house this week and don't have the luxury of my BGE here. They have a digital electric smoker that will only go up to 275°. I wish it would do 350-400, but this is what I have to work with. Anyone done a turkey this low? I'd like to get an estimate on time. (Yeah, I know... Cook to temp, but I am planning here!) I have a 15lb bird.
