Cantucci (Biscotti di Prato) vs Classic Madeleines: French Shell-Shaped Cakes

Cantucci and madeleines both utilize eggs, sugar, and vanilla to create distinct textural experiences. While cantucci rely on toasted almonds and orange for a crunchy, double-baked snap, madeleines feature unsalted butter and lemon zest for a soft, airy sponge. The shared ingredients form a base that highlights the almond's earthiness in the cantucci and the rich, citrus-brightened crumb in the madeleines. These two desserts showcase how identical pantry staples can be transformed into either a sturdy, toothsome biscuit or a delicate, moist cake.
