Welsh Rarebit (or Rabbit) is a tangy cheese sauce served over toast or cracker, perfect for a luncheon dish for the ladies or a snack for the gentle men. some rarebits call for beer or ale, but this one is made with milk. The only clue to the origin of this recipe is the word Proctors, which might be the name of the hostess who served it to the lady who transcribed it. source unknown

Whisk about 1/4 cup of the sauce into beaten eggs to temper them. Return egg mixture to rarebit and whisk to combine. Set pan over low heat and continue cooking, whisking constantly, til eggs are cooked and rarebit is heated through, about 2 minutes. Don’t boil. Add peppers if desired.
