I was looking on line for the details of what traditional mince pies were made of. I found this on Wikipedia :
The early mince pie was known by several names, including “mutton pie“, “shrid pie” and “Christmas pie“. Typically its ingredients were a mixture of minced meat, suet, a range of fruits, and spices such as cinnamon, cloves and nutmeg.en.m.wikipedia.org › wiki › Mince_…
Now they are a sweet pie with raisins and sultanas mixed peel, some form of fat which is vegetable based and possibly some alcohol.
Real Christmas treat.
