   In the fat remaining in the skillet cook the mushrooms and the garlic over moderately low heat, stirring occasionally, until the mushrooms begin to turn brown and transfer the mixture to a plate.

   Add the broth to the skillet and deglaze the skillet, scraping up the brown bits.

4. 4

   Add the cream, the ketchup, the Worcestershire sauce, and the mustard and stir in the mushroom mixture and the steak slices.
