Nobody will ever believe me, but I didn't know it was National Pie Day until after I posted a photo of my Mom's empty pie shell (shown below) on the Living the Country Life Facebook page and asked readers what filling they liked best. The response was so fast and fun that I created a poll with all the different types of pies, based on the reader feedback. Vote here: https://www.livingthecountrylife.com/what-your-favorite-pie/
I also discovered there is a National Pie Council (piecouncil.org).
For the record, I love berry (any kind of berry), tart cherry, tart lemon cream, and rhubard pie the best.
