Sheep’s head broth, brains in parsley sauce optional. Nostalgic foodies in happy-heirloom-beet-utopia claim that we shouldn’t eat anything that our Great-Great Grandmother wouldn’t recognise as food – yet it works both ways. Follow the soup with a fish custard and a jam pudding and you have the perfect 1950’s meal – in line with the dietary recommendations of the day – 1/6 of your diet as fat, 1/6 protein and 2/3 carbs. Yummy!
