See that's the thing with them: the ingredients list is quite similar to that for Christmas Pudding. I provided this on another thread some years ago:
Just wanted to start a new thread for everyone to share their favorite recipes they cook for the holidays. Don't be afraid to share the secret family recipes....we won't tell anyone!!! It will be interesting to share recipes across culture and countries.

And then there is Christmas cake, which is the same sort of mix of dried fruit etc., all over again, but with a rather evil layer of marzipan and icing on it, to make it even sweeter and more
étouffe chrétien still.
So it can get a bit samey by the end of Christmas. But one can eat mince pies in Advent e.g. after carol services, so it's possible to get some in before you get fed up with the taste of currants, sultanas etc.
