        • Heat well a frying pan. Put the seasoned steaks on the hot pan and quickly fry them from all four sides.
        • Put the fried steaks on a baking sheet and place into the preheated oven for 8–12 minutes. Remove the medium rare steaks (when the temperature in the oven reaches 50–55 ºC) from the oven, cover them loosely with kitchen paper or aluminium foil, and leave for 10 minutes.

        • Peel and chop finely the shallot bulbs. Heat olive oil in the frying pan, in which the meat was cooked, and fry there shallots.
        • Pour brandy and mix thoroughly with a cooking spatula, scraping all the stuck pieces formed when baking and frying from the pan bottom. Cook for 2 minutes, until the brandy boils, then add the cream.
