Make a quart of nicely flavored mock custard, put it into a large glass fruit dish, which is partly filled with stale cake (of any kind) cut up into small pieces about an inch square, stir it a little, then beat the whites of two or more eggs stiff, sweetened with white sugar; spread over the top, set in a refrigerator to become cold. Or, to be still more economical: To make the cream, take a pint and a half of milk, set it on the stove to boil; mix together in a bowl the following named articles: large half cup of sugar, one moderately heaped teaspoonful of cornstarch, two tablespoonfuls of grated
chocolate one egg, a small half cup of milk and a pinch of salt. Pour into the boiling milk, remove to top of the stove and let simmer a minute or two. When the cream is cold pour over the cake just before setting it on the table. Serve in saucers. If you do not have plenty of eggs you can use all cornstarch, about two heaping teaspoonfuls; but be careful and not get the cream too thick, and have it free from lumps. The cream should be flavored either with vanilla or lemon extract. Nutmeg might answer.
