To make the pastry, sift the flour and salt
together into a large mixing bowl. Add the cubes
of butter. Rub the butter and flour mixture
together with your
fingertips until
the mixture has a coarse texture.
Stirring
lightly with a knife, sprinkle water
over the dough until it just begins to cohere.
Gather the dough together into a
ball, pressing it together with your hands.
Wrap
in Clingfilm and chill for 30 minutes.
Preheat the oven to 190°C/375°F/Gas mark 5.
Boil the melon
with the wine, stirring often, until the mixture
has reduced to a puree and thickened.
Pound together the macaroons, sugar and
cinnamon, and add the melon puree. Line a
20cm/8in tart tin with the pastry dough and pour
in the melon mixture.
Bake in the oven for 30 to 35 minutes, until the
pastry is crisp and golden.
