I know that this is an old post, but I just stumbled on it and had to say
It's so funny that I found this, for two reasons. 1) I was searching for 'lamb' as I have a leg I was thinking about smoking tomorrow and, so was looking for help. But 2) I was lying in bed last night wide awake and thought . . . 'A gyro fatty! That sounds great, but how would I do it?' I've been thinking on and off all day about how to do it, and 'Eureka, I found it!!', completely by accident.
I've said it before and I'll say it again . . . I'm amazed by the quality and creativity of folks on this board!
Thanks (late) for the post!
