To Boil Ducks with Onion Sauce

Scald and draw your ducks, put them in warm water for a few minutes, then take them out and put them in an earthen pot; pour over them a pint of boiling milk, and let them lie in it two or three hours; when you take them out, dredge them well with flour, and put them in a copper of cold water; put on the cover, let them boil slowly twenty minutes, then take them out, and smother them with onion sauce.
