Add the butter, piece by piece, to the wine and
beat the mixture with a whisk until it becomes
creamy. Beat in the salt, 1 tablespoon sugar and
all of the flour, spoonful by spoonful.
Roll the
resulting dough into a ball, cover with a tea
towel and leave for 2 hours.
Preheat the oven to 220°C/425°F/Gas mark 7.
Mix the remaining sugar with the cinnamon. Roll
the pears in this mixture.
Roll out the dough to
5mm/1/4in thick and cut it into 4 squares large
enough to wrap around the pears.
Wrap each pear
in a case of dough, leaving the stems sticking
out. Brush the pastries with the egg yolk.
Put
the pears on a floured baking tray. Bake in the
oven for 25 minutes, or until the pastry is
golden. Serve hot with cream.
