Melt a tablespoon of butter and two cups of shaved cheese together; add a gill of beer or of hot water, stir until your mixture is soft and stringy, put in salt and cayenne, and serve on toast or crackers.
This is the easiest kind of Welsh rarebit and satisfies some palates entirely. To my mind it is improved by the addition of a tablespoon of Worcestershire sauce and a half teaspoon of celery salt. I have a recipe which also calls for a teaspoon of lemon juice.
No one can warrant a rarebit against stringing unless eggs are added. One or two of these, beaten light and stirred in at the last moment, will keep the cheese from becoming ropy.
