Have you ever had Shepherd's PIe?  What's in a Shepherd's Pie?
 In the States, we tend to think about shepherd’s pie (or, rather, cottage pie) around St. Patrick’s Day. So, if you ask nearly anyone what country shepherd’s pie comes from, you’re bound to get the answer, “Ireland.” However, cottage pie probably originated in Scotland, in the North of the UK. Meat pies were common in this region, and were topped with pastry crust before the 1700s when potatoes were introduced as a crop. Once the potato crust came into play, cottage pie as we know it today came into being. As cottage pie became popular throughout Britain and potatoes became a staple crop in Ireland, the dish began to be more associated with Ireland, and similar pies with a pastry crust began to re-emerge in Scottish cuisine.
