Welsh rarebit, also known as Welsh rabbit, is a traditional British dish consisting of a savory cheddar cheese sauce served on toasted bread. The cheese sauce typically includes ingredients such as beer or ale, Worcestershire sauce, cayenne, mustard, and paprika. If a fried or poached egg is added on top, it becomes buck rarebit or golden buck.
The origins of the name "Welsh rabbit" are uncertain, with the earliest known use of the term dating back to 1725. The term "Welsh rarebit" appeared later, in 1781. Some believe "Welsh" was used as a pejorative term. Another theory is that the name originated from Welsh peasants who substituted cheese for the meat they could not afford. There is also a humorous legend that says Saint Peter tricked the Welsh out of heaven with the promise of "Caws Pobi" (baked cheese).
Variations on the dish include the use of different cheeses such as Lancashire, Cheshire, or Double Gloucester. Other variations include Scotch rabbit, English rabbit and blushing bunny. Welsh rarebit is a common pub food, often paired with a pint of beer or ale.
