What is the correct name for the dish that comprises toast topped with grilled cheese and mustard?
F: Welsh rarebit
A: Welsh rabbit
Welsh rabbit' was first mentioned in 1725. ('Welsh rarebit' on the other hand, was only cited in 1785.)
It was called "Welsh rabbit" because "Welsh" was a slur in the 17th and 18th Centuries for inferior quality.
The Victorians stumbled into the trap of thinking that the dish was initially called "Rarebit" and started to note it down in recipes as "Rarebit" rather than "Rabbit"...which is why most people mistakenly call it "Welsh rarebit" today.
