Just after the War my mother had to get a new gas cooker (I suspect the first one anybody in the family ever got). It was like an old Vincent motorbike: all the pipework was on display on the outside… and it came with a cookery book called “The Radiation Cookery Book”, full of Useful Recipes for “a meal for four” using cheap ingredients. It has two recipes for Scotch Broth. (Eighteenth edition, 1935, it was. And is; I still have it, with the back cover missing.)
The family of mice living in the bottom of that cooker didn’t happen until later, when it had moved house with us and my elder brother started having mice who were all of them escapologists.
