Well, after a lot of research on the subject I have discovered that the two dishes are basically interchangeable. Some people believe that shepherd’s pie should always be made with mutton or lamb (sheep) because shepherds care for sheep. Other people consider this to be a food myth…who knew such myths existed? There seems to be some discrepancies depending on where you live. What is really fascinating is that this style of “pie” exists all over the world. What I have discovered is that there are no hard and fast rules for either of these dishes. I found recipes with peas, without peas, with carrots, with tomato paste, with celery and without. I even found recipes with cheese melted on top. The bottom line, take some minced meat (ground) add some chopped veggie and top with mashed potato – done. Here’s what I call shepherd’s pie.
