I tossed in 75g blueberries the last time I made this. It was wonderful. You can brush the top of the pastry with egg wash instead of cream, if desired.
I have just made it but as I don't have a food processor had to do it by hand. I feel that the pastry is very expensive to make given the amount of butter used and the amount of fresh fruit. Don't think I would make it again for that reason. Sorry - 06 Aug 2015
