Cromwell's Crust
A wedge-shaped crust at the end of a loaf of manually sliced bread, so shaped because the person(s) who did the slicing had been cutting at an angle instead of straightly. These crusts are named after Oliver Cromwell, the ex Lord Protector of England; it was rumoured that he habitually mis-sliced his own loaves to produce them.
I'm so angry - I came in from work for a sandwich, and all we had in was a Cromwell's Crust and half a cucumber...
