"Welsh Rarebit" was mentioned in a recent episode of " Something Rhymes with Purple " that was discussing the origins of food related words and phrases. It was originally "Welsh Rabbit", an insinuation that the Welsh were so poor that they could not even afford Rabbit, the cheapest meat available.Absolutely. Welsh Rarebit is a delicious but very occasional treat.
The change from "Rabbit" to "Rarebit" was an affectation, to make it sound a bit "Grander", as was the use of " Luncheon" instead of lunch.
