Every April 3rd National Chocolate Mousse Day recognizes the decadent dessert that gained popularity in France in the 1800s.

Mousse is prepared by beating eggs or cream or both to a frothy, airy consistency and then folding the ingredients together to create a light, creamy delight.

While mousse can be either savory or sweet, for this day, we will focus on that all-time favorite, chocolate.

The words mousse and chocolate are derived from the French language, so it isn’t difficult to believe France is where to begin looking for the beginnings of this versatile creation. While we have no exact point in time when this might have been, we do know chocolate was introduced to the French around the year 1615, and they fell in love.

Then a century later, the French developed a method for making a mousse. Savory led the way, but it couldn’t have been long before the same approach was applied to chocolate.

In the United States, an advertisement in The Brooklyn Daily Eagle in 1887 included classes on how to make chocolate mousse offered by a Miss Parloa. She also advised how to make potato soup, larded grouse, potato timbale, and corn muffins.

From dark chocolate to milk chocolate, bittersweet, or any combination, there is plenty of variety when it comes to chocolate mousse.

April 3rd Celebrated (and Not So Celebrated) History


Relay teams on horseback begin delivering the first post as part of the Pony Express. The private enterprise consisted of over 80 riders and hundreds of stations along the east-west routes that stretched from St. Joseph, Missouri and Sacramento, California. While the Pony Express only operated for 18 months, during that time it was a success. With the incorporation of the Overland Telegraph Company of California and the Pacific Telegraph Company of Nebraska, the Pony Express’ days were numbered.


Due to the absences of Supreme Court Chief Justice William H. Rehnquist and Justice John Paul Stevens, Supreme Court Justice Sandra Day O’Connor becomes the first woman to preside over the highest court in the land.
