So obviously this recipe works with all cervids, antelope, deer, moose, elk, etc. It will also work with beef and lamb, of course, but also bear and even pork -- where the effect is essentially a boiled ham.
Add everything but the roast to a pot and bring it to a boil. Turn off the heat and cover, then let it cool to room temperature while covered. This will take a few hours. Meanwhile, trim any silverskin you find off the roast. Leave the fat. Once the brine is cool, find a container just about large enough to hold the roast, place the meat inside and cover with the brine. You might have extra, which you can discard.
Make sure the roast is completely submerged in the brine; I use a clean stone to weigh the meat down. You can also just flip the meat every day. Cover and put in the fridge for 5 to 7 days, depending on the roast's size. A 2-pound roast might only need 4 days. The longer you soak, the saltier it will get -- but you want the salt and nitrate to work its way to the center of the roast, and that takes time. Err on extra days, not fewer days.
After the alloted time has passed, you have corned venison. To cook and eat, rinse off the meat, then put the roast in a pot just large enough to hold it and cover with fresh water. You don't want too large a pot or the fresh water will leach out too much flavor from the meat -- it's an osmosis thing. partially cover the pot and simmer gently -- don't boil -- for at least 3 hours and up to 5 hours. The meat itself will be cooked in an hour or less, but you want the sinews and connective tissue in the roast to soften and that takes time.
Eat hot or cold. It is absolutely fantastic with good mustard and some sauerkraut on a sandwich.
One final tip:When you are done with the corned venison, leave it in the cooking broth. Store that in the fridge. Why? The broth keeps the venison moist. Without fat, if you leave it out of the brine it can get very dry and even crumbly.
