Ways to celebrate

Chocolate mousse spent part of its history going by a name that sounds more like a sandwich spread than a dessert.

Know the dish's much older paper trail

The first documented chocolate mousse-like recipe appears in 1750, in Menon's "La Science du Maître d'Hôtel Confiseur," a professional guide for pastry chefs — printed recipes for "mousse au chocolat" continued to surface in 1768, 1814, and 1827.

Consider the painter's contested claim to fame

Post-Impressionist painter Henri de Toulouse-Lautrec, an avid amateur cook, is often credited with popularizing a whipped chocolate creation he called "mayonnaise de chocolat" — food historians now recognize it as an early version of modern chocolate mousse, though the attribution to Lautrec himself remains debated.
