I used to believe treacle came from pigs. This was an unfortunate cross-pollenation of two kitchen conversations I was listening to at the same time: my grandmother telling me that every part of a pig was usable, even the head and cheeks - and that you could get something (I think the real answer was brawn) by boiling down pigs cheeks. This overlapped with my mother muttering something about treacle, and - no pun intended - it stuck. I thought, until I was about 16 actually, that treacle was made by boiling down pigs cheeks.
