Can I make a suggestion? cut all of that fat off. every bit.
Unless you like the gamey flavor. That's were it all is.
Making #deer #jerkey for the first time. The marinade smells delicious. I just threw it in the dehydrator and by tomorrow morning we should have some jerkey ready for breakfast. #venison
Here’s the recipe I tried - https://www.allrecipes.com/recipe/46324/deer-jerky/

Thank you for the suggestion. I do taste a different flavor on some of the pieces.
You got it. I mean some people do like it. I for one can't stand it. But that is where all that flavor is.
Another tip is, for meat that you can't get all the fat and tissue off of (shoulder) render it in the crockpot for 8 hours or so. It takes care of it.
I’ll take all the tips you have. Do you have a tasty recipe?
