Hi Stig
Whatever you do, get the bone out.
Deer fat, which the bone contains lots of, has a high melt point and once cooked, does not take long to reform again. This can happen while the meat is resting after cooking or even on your plate-result is a sticky floury taste because your tounge gets coated with lots of small fat droplets. Get the bone out and you cut this down to a minimum.
Also, there is a quite large fat area, shaped a bit like a triangle, within the haunch meat and between two of the main muscle groups. You should spot it when boning out.
I always bone out the haunch and also separate the muscles groups on one side, extract the fat and then re-assemble the haunch and cook as a rolled joint, a bit like a brisket.
Try a long slow roast with some fat bacon pinned onto the joint before foil wrapping it.
I even came across a recipe the other day where you put a bit of coke or pepsi into the wrapping foil before cooking. Apparently it makes brill' gravy
enjoy
you know what they say-the longer the better! (cooking that is)
