Do not rush to put the meat in the pan!
Heat the pan itself first (hold your hand over the surface and you will feel the heat), then add a mixture of 2 types of oils and let the oils warm up! As soon as you see boiling bubbles of butter, immediately spread the prepared steaks, BUT - not all at once! There should be space between the meat. Cook the meat on each side for 3 mins For a fillet this time, enough. Salt only now, but already fried side!
Cooked meat on a platter and cover with foil (pot with lid), fry until the second portion and go. preparatory work.
