Sift the flour and salt
into a maxing bowl, make a well in the centre
and add the sugar, butter, egg, egg yolk,
vanilla essence and most of the water.
Using
your fingers, gradually work the flour into the
other ingredients to give a smooth dough, adding
more water if necessary. Wrap in Clingfilm and
chill for 1 hour.
Roll out three-quarters to the
dough and use to line a shallow 25cm/10in cake
tin. Spread the jam over the base and sprinkle
with the biscuits.
Slice the pears very thinly.
Arrange over the biscuits in the pastry case.
Sprinkle with cinnamon, raisins and demerara
sugar.
Roll out the remaining pastry and use
cutters or a knife to trim into the shapes of
your choice to decorate the top of the dish.
Alternatively, use to make a lattice.
Cook in
the oven for 50 minutes, until golden and cooked
through. Leave to cool, then serve warm or cold.
