A Historical Overview of Pumpkin Mousse
Pumpkin mousse has roots in French cuisine, where mousse (meaning “foam”) was created as a light, airy dessert. Traditionally made with chocolate, fruit, or custard bases, mousse became popular across Europe in the 18th century. When pumpkin entered the picture in American kitchens, it naturally merged with fall flavors like cinnamon, nutmeg, and cloves. Today, pumpkin mousse is a seasonal favorite—especially around Thanksgiving—offering a lighter alternative to pumpkin pie. The keto version skips sugar but keeps all the rich, spiced comfort.
