Courtesy of a link at Joel's place, we learn George Washington's recipe for eggnog.
One quart cream, one quart milk, one dozen tablespoons sugar, one pint brandy, 1/2 pint rye whiskey, 1/2 pint Jamaica rum, 1/4 pint sherry—mix liquor first, then separate [a dozen] yolks and whites of eggs, add sugar to beaten yolks, mix well. Add milk and cream, slowly beating. Beat whites of eggs until stiff and fold slowly into mixture. Let set in cool place for several days. Taste frequently.
I think I should make that this Christmas. I daresay Lawdog, Phlegmmy, Old NFO, Miss D., aepilot_jim and others will help me drink it. Of course, after imbibing it, we may not remember very much about Christmas 2016 . . . but by George (literally!), it should be worth it!
Does that explain his rosy cheeks, perhaps?
