What is "Derby pie"?

Derby pie is a dessert that is believed to have originated in Kentucky, USA. It is a rich and decadent pastry that is typically made with a filling of chocolate chips, pecans, and bourbon, all mixed together with a sweet filling made from sugar, eggs, and butter. The filling is then poured into a pie crust and baked until it is set and the crust is golden brown. Derby pie is often served as a dessert during the Kentucky Derby, a famous horse race that takes place annually, but it is also enjoyed throughout the year as a special treat. It is known for its rich, indulgent flavor and is often served warm with a dollop of whipped cream or a scoop of vanilla ice cream. The name "Derby pie" is actually a registered trademark, so similar pies made with the same combination of ingredients are often referred to as "chocolate pecan bourbon pies."
