The Cake Born from a Tax Loophole

The famous French Christmas cake, the Bûche de Noël (Yule Log cake), owes its modern popularity to 19th-century Parisian architecture. For centuries, families burned real, massive wooden logs to warm their homes for the holidays. When Napoleon III modernised Paris with smaller apartments and efficient cast-iron stoves, large fireplaces disappeared. Master pastry chefs stepped in to fill the cultural void, inventing a rolled sponge cake decorated to look like wood so city dwellers could still have their "log."
