Why is Mandarin Orange Cake called Pig Pickin’ Cake?
Despite the name, there’s no pork in this dessert! Pig Pickin’ Cake gets its name from the Southern pig pickin’ gatherings where this cake was often served.
These celebrations centered around a whole roasted pig, and this easy make-ahead cake became a favorite for feeding a crowd. Over the years, it also became known as Sunshine Cake or Pea Pickin’ Cake, depending on the cookbook.
My best guess is that Pea Pickin’ Cake came about due to regional differences, or perhaps someone misunderstood their Southern friend on the phone as she relayed the recipe! 😉
