Then set it upon the fire, and put in the whites of four Eggs to clarifie it; And as the scum riseth, take it off clean: Then put in a pretty quantity of Rosemary, and let it boil, till it tasteth a little of it: Then with a Scummer take out the Rosemary, as fast as you can, and let it boil half a quarter of an hour; put it into earthen pans to cool; next morning put it into a barrel, and put into it a little barm, and an Ounce of Ginger scraped and sliced; And let it stand a Month or six Weeks.
