It always annoyed me that plum bread never actually contained any plums. I used to think that it was like mince meat pies - the pies used to contain meat, but it was slowly phased out and replaced with fruit. I recently learnt, however, that there never were any plums in plum bread; the reason for the name actually stems back to the 18th century. It turns out that during the Victorian period, raisins were actually called plums. I love finding out about the history of words, and how it links up to how our language works today.
Anyway, the mystery might be solved, but I still find the fact annoying. I therefore made my own recipe for plum bread that yes, indeed contains plums. Based on brands I used, each slice is about 124 calories.
