Origin and Cultural Significance
Rooted in European dessert traditions, Lemon Mousse Cake blends French mousse techniques with the citrus reverence found in Italian and Mediterranean cuisines—particularly the Amalfi Coast, where lemon groves flourish. Lemon is often associated with purity, brightness, and refreshment, making lemon-based desserts a symbol of light indulgence. Over time, this cake has evolved into a favorite for bridal showers, Easter brunches, and warm-weather festivities.
