do you know how old the boar was?
If it's less than a year there is no need for marinating, if it's older it might be better ;o)
If you're not sure, it might also be better ;o)
classical boar herbs are (crushed) juniper, bayleaf, rosemary, thyme. rub the haunch and marinate over night, you may add dry red wine.
LiGruess cara ~~~ Life should NOT be a journey to the grave with the intention of arriving safely in a well preserved body, but rather to skid in sideways, chocolate in one hand, wine in the other, totally worn out and screaming "WOO HOO what a ride!"
