To make the
pastry, sift the flour and salt into a large
bowl. Make a well and add the butter, egg
yolk and icing sugar. Work together the butter,
yolk and sugar with your fingertips, then
incorporate the flour.
Bring together into a
ball, adding water if the mixture is too dry.
Cover with Clingfilm and refrigerate for 20 minutes.
Preheat the oven to 200°C/400°F/Gas mark 6.
Lightly grease a 20cm/8in loose bottomed
flan tin. Roll out the pastry between 2
sheets of baking parchment until it is 3mm/1/16in
thick, to fit the base and sides of the tin.
Trim the edge and chill for 10 minutes. Line the
pastry with aluminum foil, fill with baking
beans and bake for 10 minutes. Remove
the foil and beans and bake for another 6 to 8
minutes, or until the pastry looks dry allover.
Cool the pastry and reduce the oven temperature
to 150°C/300°F/Gas mark 2.
For the filling,
whisk the eggs, yolks and caster sugar together,
add the cream and juice and mix well. Strain
into a jug and then add the lemon zest.
Place
the
flan tin on a baking tray on the middle shelf of
the oven and carefully pour in the filling right
up to the top. Bake for 40 minutes, or until it
is just set.
Slice the lemons very thinly.
Combine the granulated sugar and the water in a
small frying pan and stir over a low heat until
the sugar has dissolved.
Add the lemon slices
and simmer over a low heat for 40 minutes, or
until the peel is very tender. Lift out of the
pan and drain on baking parchment. Cover the
tart with the lemon slices and serve
immediately.
