IDS, I do trim the valves out before smoking,try smoking one for something different.Awesome looking deer heart crazymoon! I've grilled a bunch, never smoked one though. I see you trimmed some of the fat. Did you also trim the valves too?
I too save the hearts and will ask friends if they want the heart from the deer they shoot. It is an underrated cut on a deer....
Looks delicious!
We love deer hearts and liver.
Truth be told, from most any critter, yum.
