Macaroni and Cheese, No. 1

One cupful of macaroni, broken into small pieces,
2 quarts of boiling salted water,
1 cupful of milk,
2 tablespoonfuls of flour,
¼ to ½ pound of cheese,
½ teaspoonful of salt,
speck of cayenne pepper.
Cook the macaroni in the boiling salted water, drain in a strainer, and pour cold water over it to prevent the pieces from adhering to each other.
Make a sauce out of the flour, milk and cheese. Put the sauce and macaroni in alternate layers in a buttered baking dish, cover with buttered crumbs and heat in over until crumbs are brown.
