Welsh rarebit

Welsh rarebit or Welsh rabbit is a dish of hot cheese sauce, often including ale, mustard, or Worcestershire sauce, served on toasted bread. The origins of the name are unknown, though the earliest recorded use is 1725 as "Welsh rabbit" (possibly ironic or jocular as the dish contains no rabbit); the earliest documented use of "Welsh rarebit" is in 1781. Variants include English rabbit, Scotch rabbit, buck rabbit, golden buck, and blushing bunny. Though there is no strong evidence that the dish originated in Welsh cuisine, it is sometimes identified with the Welsh caws pobi 'baked cheese', documented in the 1500s.
