A Tom and Jerry is about as classic as you can get when it comes to traditional holiday drinks. Dating back to the 19th century, the drink is even served in special mugs. Similar to eggnog, made-to-order Tom and Jerrys come together by folding a batter of whipped eggs, sugar, rum, and spices into even more alcohol, hot water, and milk. A definite cold-weather treat, it's frothy, rich, creamy, and sweet.
Healthy alternative: If you're craving the flavor of a Tom and Jerry minus the fat and sugar, start with this light eggnog recipe. Instead of chilling the eggnog, at the last step, fold the whipped egg whites into the drink while still hot. Serve immediately.
