Eggnog was extremely beloved in the Medieval Ages, known as a Posset.
Posset was a warm, creamy, ale-like drink and was the forerunner to today’s spicy eggnog. In fact, Posset was so trendy that they even had one made without cream, called a caudell. The caudell was literally wine thickened with eggs. The ingredients for eggnog – milk, eggs, wine/sherry, and figs later on – were so expensive back then that eggnog was mostly used to toast good health. It did not become a Christmas party drink until it hopped across the pond in 17th century America.
Closest to that medieval taste: None, really – let me know if there are – because these days we put rum and other hard liquors in our eggnog. But, cool medieval recipe for those medievalthusiasts out there: the Caudell Recipe.
