oven to 200'C/400'F/Gas 6. Mix the plums with
the kirsch or brandy and set aside for about 30
minutes.
Roll out
the pastry thinly and use to line a 23cm/9in
pie tin. Prick the base of the pastry case
all over and line with foil. . Add a layer
of baking beans and bake for 15 minutes
until slightly dry and set. Remove the foil
and the baking beans.
Brush the base of
the pastry case with a thin layer of jam, then bake
for a further 5 minutes. Remove the pastry case from
the oven and transfer to a wire rack. Reduce the
oven temperature to 180 'C/350 'F /Gas 4.
To make the
custard filling, beat the eggs and sugar until well
combined, then beat in the cream, lemon rind,
vanilla and any juice from the plums.
Arrange the
plums, cut-side down, in the pastry case and pour
over the custard mixture. Bake for about 30-35
minutes until a knife inserted in the centre comes
out clean. Serve the tart warm or at room
temperature.
