Remove the steak from the fridge approx. 30 mins. prior to frying. Preheat the oven to 60 °C to warm the plate. Season the meat. Heat the clarified butter in a frying pan, fry the meat for 3-4 mins. each side and transfer immediately to the warmed plate.
Distribute the tomatoes and rocket on a platter. Slice the meat and lay on top. Top with the pesto and Parmesan. Garnish with basil and Fleur de Sel.
