Eataly shares a different story: 12-year-old Toni worked for the Duke of Milan’s head pastry chef, who was in charge of creating dessert for the Christmas Eve Feast. The pastry chef ruined the dessert, but Toni saved the day by adding butter, sugar, and citrus fruit to the leftover dough to create a pastry that eventually became known as pane di Toni, or Toni’s bread.
