As I understand it, bison are often raised for meat nowadays.

Even some grocery stores carry bison. I don't care for the burgers, but chunks make a delicious stew.

You need to add some pork fat. Bison is very low-fat meat, and in burgers or steaks, it tastes dry, dry, dry. Like powdered toast.

Add some pork (or beef) fat to the burger meat and it gets real tasty.
