Wash off the pollack fillet. Place on paper towels and pat dry. Carefully pull the bones with the bone tongs. Divide the fillet into 3 to 4 pieces, depending on the size. Season with salt and pepper and let it steep for a few minutes.
Heat the oil in a coated pan. Flour the fish pieces and turn them in the beaten egg. Put the skin side into the hot oil and fry for about 5 minutes. When the skin is golden yellow turn over and continue to fry briefly over medium heat. Finally add a trick of butter and toss the fish in the butter. Turn off the stove and let the fish steep for about 5 minutes.
We prefer to eat boiled potatoes and salad with this, as the taste of the fish comes into its own.
