Set one quart of milk on to boil as before directed* (see note).
Scrape with a knife one ounce of nice chocolate, and mix with one heaping cup of sugar;
wet this with two spoonfuls of boiling milk;
work this into a paste with the back of the spoon, and stir into the boiling milk,
and then stir in six well-beaten eggs; stir three minutes,
and then strain.
Set in cold water and stir occasionally, until cold, then sir in two teaspoons of vanilla. Serve in glasses.
