Rompope is a traditional eggnog-like drink that is popular in Mexico and other Latin American countries. It is made with milk, sugar, cinnamon, cloves, nutmeg, eggs, vanilla extract, and baking soda, and is typically served with rum or brandy. The egg yolks give the drink a yellow hue and help emulsify everything. The word "rompope" is a derivation of the word "rompon," which is used to describe the Spanish version of eggnog that came to Mexico.

Rompope is believed to have been originally made in the convents of the city of Puebla, Mexico, during the Colonial period. According to tradition, the original Mexican rompope beverage was created in Pueblas Convento de Santa Clara in the 17th century. Rompope is made commercially throughout Mexico, all year long, but many locals prefer to make it at home. Several ingredients are sometimes added to the drink, including pecans, almonds, walnuts, pine nuts, strawberry, and other local ingredients.

To make rompope, milk, sugar, cinnamon stick, cloves, and nutmeg are heated over medium-high heat while stirring constantly with a wooden spoon or spatula. This is to prevent the milk from sticking to the bottom of the pot. Egg yolks are then added to the mixture, and the mixture is cooked at an almost boiling temperature. The drink is then strained and cooled before adding rum or brandy.

Rompope is a festive drink that can be enjoyed warm or cold, with or without alcohol. It is typically served during the holidays in Mexico, but it is also enjoyed throughout the year.
