To get the wild taste out, it helps to soak it in salty water. If it's frozen, let it thaw on it's on. Helps make it a little more tender.
I like to fry the tenderloins/backstraps. Slice them into small pieces, soak them in egg, roll them in flour and put them in just enough oil to make cover half of the meat. While frying, add Worcestershire sauce and hot sauce, plus whatever seasoning you like. Fry until golden brown.
That concoction made my dad go off his diet.
