Firstly, don't forget to get your cast iron heating up. I used about 1/3 of a pound of ground venison for two burgers. I mixed in half a packet of off-brand onion soup mix...doesn't matter what brand, or you can use some of the home-made stuff. Mix it all together with your hands and form it into patties.
Put them in your pre-heated skillet and sprinkle with a little sea salt and black pepper.
Splash about a tablespoon of Worcestershire sauce over each, and cook until done all the way through. The pokey trick you use with steaks and regular burgers works the same here.
Put on a bun with whatever you want...Mustard, mayonnaise, lettuce, tomato, and pickle shown here. Mine is the picture up top with onions instead of pickles because I think pickles are of the devil. Whatever your poison, just dress it up like you would a beef burger. Nom.
