So what is Eggnog? Buy the carton kind and most likely it will have neither Egg nor Nog but a whole lot of artificial sugar.
However, you can mix up batch with fairly simple ingredients. Traditional recipes call for: Egg Yolks, the number varies (4 per quart) but they are left raw. Sugar not too bad compared to other desserts but still ¾ cup would not be safe on most diabetic diets. The main foundation for the drink is 2 parts Whole Milk to one part Heavy Cream. Top with nutmeg and you have a family friendly drink. If it’s just for the grown-ups Bourbon/Rum or Cognac gets added. Although legend has it George Washington liked his with Rye Whiskey, Jamaican Rum and Sherry…No wonder his teeth went bad!
