RE: Deer meat - " Gamey" taste
Draw the blood out with the salt water then sprinkle with garlic powder and pepper let sit in fridge couple hours then grill. Maybe just serve her the Backstrap or chops as some people call them. Make sure there is no fat, silver skin or bone in her piece or for yours as far as that goes . There should be no strong taste to begin with. maybe it was freezer burned.
