The Lazy Cook

This comes from Nigella Lawson.and she in her turn got it from a famous Italian food writer Anna del Conte.  Simplicity itself, it's spaghetti with Marmite.  Cook the spaghetti as normal, and strain, retaining about a ladle full of the cooking water.  Melt the Marmite in a pan with a little butter and add the cooking water and then add that to the spaghetti.  Serve with some grated Parmesan.  Buon appetito!
