A festive beverage recipe from the 1955 Michigan Consolidated Gas Company “Christmas Greetings” cook book.
Not what we would think of as Eggnog. More like a German egg punch (Eierpunsch) and an Orange Julius. The eggs beaten to ribbon stage added lightness. The recipe suggested serving over cracked ice.
I imagine wine or spirits could be added. Seltzer, lemon-lime soda, or Ginger ale would also be good.
