Rompope
It is believed that in the eighteenth century, egg whites were used as a sort of glue to bind sheets of golden and white gold. There were many leftover yolks that were then used to create various sweets and to thicken others, such as rompope. This eggnoglike beverage is wonderful served cold year-round. I like to put it in the tres leches mixture (page 142), use it to top ice cream, and make a gelatin with it (page 138). It is still sold in many convents around Mexico. Estela Romo de Vivar makes one of the tastiest almond versions I’ve had.
