To
make the pastry, sift the flour and salt into a
bowl. Rub the fat into the flour
until the mixture resembles breadcrumbs, then
mix in the sugar.
Beat
the egg yolk with the water and stir in to bind
to a fairly firm dough, adding a little more
water if
necessary. Knead lightly until smooth but do not
overwork.
Cover
and chill in the refrigerator for at least 30
minutes before rolling out.
Grease eight
deep 5 cm/2 inch muffin tins.
Roll out the pastry thinly. Cut out 7 cm/3 inch
rounds and use to line the muffin tins.
Line
the pastry
cases with foil and fill with baking beans. Bake
'blind'in a preheated
oven,
200°C (400°F), Gas Mark 6, for
12-15
minutes until set but not brown.
Remove from the oven and lift out the foil and beans. Lower the heat
to 160°C (325°F), Gas Mark 3.
To make the custard, warm the milk over
a low heat and while it is heating
beat
together the eggs
and sugar. Stir the warm milk into the beaten
eggs
and flavor with vanilla extract.
Strain the
custard into the partially baked tart cases.
Sprinkle the tops with grated nutmeg and return
the tarts to the centre of the oven for
15-20
minutes until the custard is set. Serve cold.
