Put half of the mix in a different bowl and add a teaspoon of brown sugar, rub over the steaks. Wrap loosely in foil to let air circulate, seal well and put on a roasting tray. Cook for 20 min then open the foil and cook for extra 2 min. If you like it well done give it a little extra time in foil. Serve with the olive, tomato and mint sauce.
