Add demi-glace, mustard, Worcestershire sauce and tomato paste to the pan.

Bring the mixture to a simmer then add the cream. Bring the sauce back to a simmer and reduce for approximately 6-8 minutes. It should be ready as steak is coming off the grill.

Filet Diane
10 ounces filet mignon
½ ounce unsalted butter
4 ounces mushrooms, sliced
3 ounces Filet Diane sauce
1 pinch fresh parsley, chopped
Grill or broil the steak to desired temperature.

When the steak is almost ready, place butter in sauté pan and begin cooking the mushrooms. Sauté the mushrooms for approximately 3 minutes or until cooked, but not browned.

When the mushrooms are cooked, add the sauce into the pan with the mushrooms. To ensure sauce is not over-reduced, do not prepare the sauce too far in advance. If the sauce is too thick, add a little water to correct it.
