What is the origin of panettone?

According to legend, the Christmas dessert was born in Milan at the end of the 15th century. On Christmas Eve, the Sforza cook accidentally burned the dessert he had prepared for dinner. The servant, a certain Toni, took his loaf of yeast, mixed it with flour, eggs, sugar, raisins and candied fruit and after a long leavening, put it in the oven. The “pan di Toni” was a great success.
