Jam: A True Story by Margaret Mahy, illustrated by Helen Craig, 1985.

Mr. and Mrs. Castle have three children and live in a house with a plum tree in the backyard. When Mrs. Castle gets a new job, Mr. Castle is proud of her and decides that he will stay home and look after the children. Mr. Castle likes being home with the children, and he does all sorts of useful things around the house.

One day, he realizes that he’s been so efficient at getting things done around the house that he’s run out of things to do. While he’s thinking about what to do next, he hears an odd sound. It turns out that the sound is ripe plums from their plum tree, hitting the roof as they fall off the tree.

Mr. Castle gathers up the ripe plums and makes plum jam. His family loves it, so the next day, when many more plums have fallen, he gathers those up and makes even more plum jam. As more and more ripe plums fall from the tree, Mr. Castle can’t stand to see them go to waste, so before long, the family has far more plum jam than they have jam jars.

Then, comes the real challenge: eating all the jam. As the weeks go by, the family eats jam with everything, and Mr. Castle makes many recipes involving jam, but there’s still plenty of jam left. They try everything they can think of to use up all the jam, including using it to re-tile the bathroom, but there’s just too much jam! It gets to the point that family members are starting to have jam-related nightmares!

Will they finish all of their plum jam before the plums are ripe again? Will they ever be able to eat anything without jam ever again?

The book is available to borrow and read for free online through Internet Archive. The book also includes a simple recipe for plum jam.

My Reaction

This story is funny, especially because it’s supposed to be “a true story.” I have the feeling that the author’s family had a similar incident where an experiment in jam-making went too far and became overwhelming. The family in the story eats jam in various ways to use it up, and Mr. Castle even uses it for handyman projects, like fixing a leaky roof or gluing down bathroom tiles. They never mention the idea of selling the extra jam or giving it away as gifts, probably because those ideas would make too much sense and would help solve the problem, and the story is meant to be silly.

Besides how overwhelmed the family feels about the amount of jam they have to eat, there are plenty of other funny things happening in the story. Mrs. Castle’s new job is with some scientists who are “developing an electronic medicine to cure sunspots.” It doesn’t make any sense, but the story emphasizes how proud Mr. Castle is that his wife is so clever, and the topic of sunspots appears throughout the rest of the story as a running gag. I also thought it was cute how Mr. and Mrs. Castle refer to their children, the little Castles, as being “Cottages.”

There is minor mention of alcohol in the story. There are a couple of points in the story where the parents are mentioned as drinking sherry, which isn’t very common the US. I checked, and the author, Margaret Mahy, was from New Zealand.
