While grill heats, rub steaks with olive oil and season to taste. Grill steaks over medium hot flame to rare or medium rare (approx 9-15 minutes.)
Meanwhile, prepare the demi glace according to package directions. Add the berries and cook to break down berries and marry the sauce. Taste and adjust with spicy Primo or Tony’s Organic Blueberry Preserves.
Remove from heat and swirl in butter, if using, and serve immediately over grilled steaks or burgers.
Notes: For an extra flavor kick, add 1-3 TBS (to taste) of Primo Spicy Blueberry or Blackberry Jam or Tony’s Organic Blueberry preserves
Red berries are a natural paring for Bison meat.
