This is just straight-up backstrap section. I rub a little olive oil on it, then some herbs and grill it.
Tenderloins (I call 'em weasels) get the same treatment, but get stuck on and draped around green sticks. The tops cook first when you lean them over the fire, and you just take a bite when it looks done and then return the stick to its place to cook the next section. This is a relaxed and natural way to eat meat, giving you time for sitting and conversing or doing little chores while your next bite cooks.
Tender cuts like backstrap are great butterflied and seared in the pan, served with a makeshift Marsala sauce (using homemade jellies or canned whole-berry cranberry sauce), green beans and mashed potatoes.
Liver and onions are a camp favorite, sliced thick and seared, and still pink on the inside. Heart meat can get either fried up with a wine sauce or put into spaghetti sauce.
While I am in camp, I like to roast ribs over the flames of the fire. The fat is mostly removed from the meat this way, and they are savory with woodsmoke. This also saves me a lot of picky work over them at home. Nothing like sitting at the fire snarfing hot ribs and tossing the bones into the coals! When you get a fatty bit, just put it back on the grill 'til you like its looks again.
I am getting mighty hungry sitting here!
