Eggnog

Creamy dairy-based beverage

Eggnog (or egg nog), historically also known (when alcoholic) as milk punch or egg milk punch, is a rich, chilled, sweetened, creamy dairy-based beverage traditionally made with milk and/or cream, sugar, whipped eggs (which gives it a frothy texture) and, in some contexts, distilled spirits such as brandy, rum or bourbon. Eggnog is traditionally consumed throughout Canada and the United States at Christmas every year, often from American Thanksgiving through the end of the Christmas season. During this period commercially prepared eggnog is sold in grocery stores in these countries.
