Chocolate Sauce. No. 1. (Cataldi.)
This requires the yolk of 1 egg, the whites of 3, some chocolate
(not too much) and some sugar.
Break the yolk of an egg into one stewpan, and the whites of
3 into another stewpan; sweeten the yolk of egg to your taste,
add to it some grated chocolate, and stir it in the bain-marie
whilst you whip up the 3 whites with an iron whisk, in a very
gentle heat, to a stiff froth. Then mix all together.
Whip well together, and, when hot and light, serve in a sauce
boat with any light baked or steamed pudding.
