Welsh Rarebit

I feel cheated. I've eaten melted cheese on bread, but this was so much better. Much folklore exists as to why this dish is called rarebit and not rabbit, with most explanations positing that Welsh poverty forced that subset of the population of Britain to substitute meat with cheese.

Perhaps they simply realized that this tastes much better than rabbit.

As you can see, there's very little instruction in the recipe. This one is actually quite detailed in comparison to others written down by Great-Grandmother Alice. Basically, I melted everything in a pyrex bowl over a pot of boiling water.

In case you can't read the original, above, here is is again:
1/2 lb. cheese[,] 2 eggs, speck of cayenne[,] 1 tablespoon butter[,] 1/2 teaspoon of salt, teaspoon of mustard[,] 1/2 cup milk[.] [B]reak cheese in small pieces and put it and other ingredients into a saucepan over boiling water stir until the cheese melts serve on toast[.]
