This week Nigella revisited some favourite dishes from her past and gave them the express treatment. She relived her student days with a friend, tucking into a rich, indulgent fondue and a cheesecake for pudding. Then the 'domestic goddess' was in her element cooking a 1950s-inspired dinner of crunchy fish goujons followed by boozy Crêpes Suzette - dishes that are too good to be relegated to the annals of cookery history.
