Eggnog has its roots in medieval Europe, where a similar drink called posset was popular. Made with milk, cream, and eggs, posset was a wintertime treat that was often served at special occasions. But how did it make its way to America, and become the eggnog we know and love today?
Well, it's believed that English colonists brought their posset recipes with them to the New World, where they adapted to the available ingredients. They started using rum and sugar to give their posset a little extra kick, and soon a new drink was born. It was called egg and grog, and it was a hit with the colonists.
But what about the name - where did eggnog come from? Some people think it came from the colonial practice of serving the drink in small wooden mugs called noggins. Others believe it's derived from the Dutch word eienog, which means "eggs and milk". Either way, the name stuck, and now we have a delicious drink to enjoy during the holidays.
