To Make Sack-posset Or Sack-cream
Take twelve Eggs, (the Whites of but six) beat them, and put to them
a Pint of Sack and half a Pound of Sugar; set them on a Fire,
keeping them stirring 'till they turn white, and just begin to
thicken; at the same Time on another Fire have a Quart of Cream,
boil and pour it into the Eggs and Sack, give it a Stir round, and
cover it a Quarter of an Hour before you eat it: The Eggs and Sack
must be heated in the Bason you use it in, and the Cream must boil
before you set on the Eggs.
