Here's how to cook venison. First, you need to:
a) acquire a suitable gun or bow.
b) acquire enough proficiency with said weapon to consistently place your shots into a 6-8" circle at the ranges you'll be hunting at.
c) learn where deer keep their heart and lungs, and learn to visualize that location from all angles. Learn which angles not to shoot from.
d) find some hunting grounds with some deer on them and obtain the right to hunt legally on them.
e) acquire appropriate clothing and boots.
f) acquire a treestand.
g) obtain your hunting license and deer tags; if you're hunting for meat, make sure that you get antlerless tags.
h) scout your hunting grounds to get a handle on what the herd is up to.
i) wait until hunting season.
j) get time off work during hunting season.
k) set up your stand ahead of time.
l) practice scent management and discipline.
m) make it out to your stand well ahead of hunting hours on opening day.
n) wait for a deer to wander by within range and present you with a good shot.
o) accurately place a shot into your deer's cardiovascular system.
p) wait half an hour.
q) track the deer down.
r) poke the deer into the eye with a stick.
s) if it reacts, kill it properly.
t) gralloch it (which reminds me that I forgot to mention acquisition of a good knife and learning deer anatomy and how to field dress a deer).
u) haul the deer out of the woods.
v) get the deer home.
w) butcher the deer (for which you'll need knives, saws, paper, plastic bags, a freezer, etc.).
Then, at that point, you should start thinking about recipes :).
My experience with deer hunting has involved frustration due to
a) having a hunter just downrange of a nice four pointer my very first morning out ever and not being able to take a shot.
b) the next season, having a small herd of does and fawns prance around within easy, easy range (20'-40'), but being unable to shoot them due to only having a buck tag (I did shoot some video, though: http://www.youtube.com/watch?v=dcb-bNZs7_g ).
c) being horribly busy and not able to get out for more than a few hours during deer season the season after that.
d) seeing all sorts of deer out of range, out of season, or before/after legal hunting hours, every year.
e) missing all of deer season last year due to an injury.
Deer hunting is not a trivial enterprise. Nor is it easy. A one-day seminar will only show you the beginnings of a number of subjects which you will have to learn in-depth in order to have a chance at success. You will have to invest a lot of time at the range practicing your shooting skills, more time in learning how to track and learning the woods, yet more time in studying deer behaviour and biology, and a fair bit of money in arms, ammo, and equipment. Deer hunting is, however, one of the best ways to spend your short time on this earth and I can't recommend it highly enough. I've been out for three seasons, haven't managed to bag one yet, and loved every second, including the bored, wet, muddy, and freezing cold ones.
Have you considered small game hunting? Grouse, pheasant, rabbits, squirrel and groundhogs are all tasty and easily taken with a shotgun, and small game hunting just involves wandering around in the woods and tracking. And a lot of the skills carry over into big game hunting.
