I was just reading Angela's blog at Tracing Rainbows http://angalmond.blogspot.com/ and was quite amused at Mrs Beeton's Toast Sandwich.  I followed the links to other articles about it: http://www.bbc.co.uk/news/magazine-15760897  This article talks about other austerity/wartime meals too.

This article included a further link to a recipe for carrot jam also by Mrs Beeton:

This promises two jars of jam for every pound of carrots used but uses lots of lemons.  I made carrot jam once and found that everybody liked it very much - until they were told it was made from carrots.  I liked it myself.  John Seymour has a recipe for carrot jam or was it carrot and lemon marmalade in one of his books.  I've made that too.  Next time I happen on a bargain bag of lemons, I must look the recipe out.

This is a link to apricot, carrot and almond jam from Dan Lepard. I like the sound of this one.  I remember carrot jam tasting something vaguely apricot-ish.
