Star-Topped Mince Pies

Our answer

Nigella often uses vegetable shortening in pastry (pie crust) recipes as it gives a slightly flakier texture to the pastry. This is partly as shortening has a lower water content than butter. If you can't get vegetable shortening then it would be fine to use the equivlent quantity in extra butter for the Star-Topped Mince Pies (from Nigella Christmas).

Another possible alternative, if it is available, is to use lard. This is an animal fat but is very similar to vegetable shortening in the way it works in pastry. However some people feel that the flavour of lard is better suited to pastry for savoury dishes so if you are not sure then use extra butter.

We would suggest chilling the assembled mince pies before baking them as this can help to give a flakier pastry if you use all butter in the pastry.
