This is an old English recipe from my husband's great nanny. I have made it countless times. It makes any dinner party cozy and you will get lots of raves.Make it ahead of time and reheat in oven and serve with a crisp salad. Any child who likes a crust will love it. Each slice is deep with the filling and it stays together beautifully. It is my family's favorite recipe and I make it all seasons.You might have enough filling for two pies. Note: recipe reflects a change in cook time for filling: 25 min. or until potatoes are tender.
