Rompope or Mexican Eggnog is believed to have been born in the city of Puebla de los Ángeles in the convent of Santa Clara, created by Poor Clare nuns, who were in charge of preparing drinks and dishes for the highly esteemed guests who stayed in the convents. The mixture of several ingredients such as egg, sugar, milk, cornstarch along with almond and rum gave rise to what we know today as eggnog, and although today you can find a variety of flavors such as vanilla, cinnamon, pistachio and coffee .
