Mushroom filled Beef Knuckle Ravioli

1. Separate the 3 pieces of the knuckle, cut into small steaks and flatten them until they are very thin.
2. Sauté the mushrooms in a pan and add the cream, let it stand and for an hour.
3. Lay out the steaks in the cooking table and place a spoon in the middle of the steaks, bend the steaks inward as if they were raviolis.
4. Bread the steaks with egg and panko.
5. Deep-fry the raviolis.
6. Drain the remaining oil and serve.
