Rompope, also known as rompopo, rumpopo, or rum popo, is an eggnog drink made with eggs, milk, vanilla flavouring, and rum.[1] The egg yolks impart a yellow hue to the emulsified beverage. It is a traditional drink enjoyed throughout Central America, Mexico, and Ecuador, most commonly around Christmastime.[2] In Mexico, it is believed to have been originally made in the convents of the city of Puebla, Mexico. The word rompope is a derivation of the word rompon, which is used to describe the Spanish version of eggnog that came to Mexico. The Spanish version utilizes rum as its main ingredient, hence the root of both rom-pon and rom-pope. For example, Salcaja, in Guatemala, offers one known version of this rompope drink and in South America, the country of Chile has among its most popular drinks rompon and cola de mono or monkey's tail, the latter containing coffee, making it dark instead of yellow, but also containing the other ingredients commonly found in rompope.
