The singer Marietta Alboni often dined on two whole chickens, two rumpsteaks and a soup tureen full of macaroni. She must have been doing something right because Rossini was so impressed by her voice that he personally taught her the contralto r├┤les in his operas. Not only that, but in 1848 she crowned her successes by triumphing in a baritone r├┤le at Covent Garden.
