My best backstrap recipe so far has been this:
Butterfly and beat flat. Then fill with cream cheese mixed with mushrooms and chopped jalepeno. Fold close and wrap with bacon.
Bake in over at 400 for 20 mins.
I have tired that on a smoker. It is delicious, but it gets dried out a little bit on a smoker or grill if you aren't watching it like a hawk. I will have to try that in the oven. I have two processors that I use. One of them cuts venison steaks to perfection and does an overall better job with letting them hang in the freezer and processing the meat. I get all my steaks, cube steaks, stew meat, and all other cuts like that from Whitt's.
Bucks I use strictly for the jerky and summer sausage. I let him give me the back strap, tenderloin, 10lbs of summer sausage, 10lbs of jerky, roast and do the rest in burger and sausage. No specialty cuts. His summer sausage and jerky are on point. He uses pepper jack, cheddar along with the Jalapeno peppers and a Cajun seasoning.
