How to make
Tenderize the steaks with a mallet. In a bowl, mix the mustard, mayonnaise and spices. Smear the steaks with the resulting mixture and put them in the fridge for a few hours.
Pour a little oil in the pan and braise the steaks briefly on both sides. Arrange them in a clay pot.
In the same pan, saute the chopped mushrooms. Once they begin to change color, pour in the cream and leave them to come to a boil.
Dilute the flour with the water and add it to the mushrooms. Stir well and pour this over the steaks. Cover the clay pot and cook at 430°F (220 °C) for about 30-35 min.
