1. Preheat oven to 500 degrees. Let the bison steaks rest 1 hour at room temperature.

Add the broth and cooking wine to the pan juices in the roasting pan scraping up the brown bits. Bring to a boil, and then reduce to simmer cooking the broth until it is reduced by half. Stir the arrowroot mixture and add it to the gravy, stir until dissolved. Simmer the gravy for 3 minutes, add salt and pepper to taste. Transfer the gravy to a heated sauceboat.
