I don't cook liver ofter but I like to stir fry it with onions & green pepper in a cast iron wok on the kettle. It gets a slight "grill" flavor. Maybe you could add smoke wood to give it a greater hint smoke flavor but in such a short cook I wouldn't expect much.
James: I was thinking cold smoke a whole liver then slice and
Mark:fry in a cast iron skillet
I haven't cold smoked in a long time and haven't seen a whole clves liver....we usually get them sliced and frozen-must not be a market for them any more.
