It's not anything I have ever made before and I didn't have a recipe for it myself but saw one on Catherine s blog at 'Living The Gourmet' here.
I just put a link in for the recipe and feel no need to write it out myself. If you have never been over to Catherine s blog before it is well worth a look, She submits some wonderful recipes and I have tried many from her and her daughter Tammy who often puts recipes on too.
The pie cooked well and looked lovely in presentation and it was a nice taste and texture but personally for me I found it a little bland. It is all down to personal taste I know so if you decide to give it a try I urge you to stick with the original recipe first as everyone's tastes are different. My Dad thought it was great!!
I think when I may it again I will try adding some ginger to it and probably do a straight pastry base as I found the one used a little sweet for my tastes.
Enjoy your day!!
