My nan was quite enlightened on that score. On special occasions we'd go round her's and be treated to her specially-prepared French cuisine.
Still get quite misty-eyed when I recall my dear old nan's L'ARD.
Macaroni cheese never used to anything other than your nan gave you when you went round her's. Just like no self-respecting food outlet would demean itself by putting fish finger sarnie on its menu, no matter how ironically.
