Where did this recipe come from?
It was invented by flamboyantly moustachioed restaurateur Alfredo di Lelio in Rome in 1908. Fame rapidly spread, and the restaurant became a magnet for royals and celebrities. Two restaurants now claim to be the authentic Alfredo – Alfredo alla Scrofa and Il Vero Alfredo (‘The Genuine Alfredo’). Film buffs should head to the latter, in Piazza Augusto Imperatore, where the walls are lined with photos of John Wayne, Frank Sinatra, Orson Welles, Ginger Rogers and Elizabeth Taylor (and countless others) eating the famous dish.
