Saw this jam on the shelf in the supermarket today, next to fig and sour cherry. There's been some recent discussion of the book French Kids Eat Everything (for example, the Huffington Post has an article about it), and the irony of seeing this right after reading that discussion wasn't lost on me.
In fact, I'm not even sure it was ironic. A nation that can offer rhubarb, fig, and sour cherry jam on its supermarket shelves is certainly a nation that has different culinary expectations for its children than the United States. An American "Good Mother" would not be serving her children rhubarb jam!
