Peppercorn Sauce for Bison Steak
Season filets with salt and pepper. Place the filets on the grill at a 45 degree angle to establish nice grill marks. Cook until the filet reaches an internal temperature of 125-130 degrees for medium rare.
1 cup white mushrooms, chopped
½ cup shallots, chopped
3 tablespoons green peppercorns (or 1½ teaspoons crushed black peppercorns)
¼ cup olive oil
1 quart demi-glace
½ cup heavy cream
Cornstarch, as needed
In a saucepan over medium heat, sauté mushrooms, shallots, and peppercorns in oil. When shallots are tender, add demi-glace and cream. Reduce until desired thickness.
