Meyer lemons are unusually fragrant and thin-skinned and have lower acidity than the more common Eureka and Lisbon lemons. A dessert mousse is a form of dessert typically made from egg and cream (classically no cream, only egg yolks, egg whites, sugar, and chocolate or other flavorings), usually in combination with other flavors such as chocolate or puréed fruit. Once only a specialty of French restaurants, chocolate mousse entered into American and English home cuisine in the 1960s.
