Put the
sun-dried tomatoes into a small bowl and pour
over enough boiling water to cover. Set aside
for 20 minutes.
Meanwhile,
put the leeks into a saucepan with the white
wine, bring to the boil and simmer until all of
the wine has evaporated.
Remove the
leeks from the heat and stir in the milk, egg
yolk and soft cheese, and season well with salt
and pepper. Brush a pastry square with a little
egg white and use it to line the base and sides
of a 10 cm/4 inch tart case.
Brush two
more squares and lay these on top, each at a
slightly different angle from the first,
allowing the edges to flop over the rim. Line
three more tart cases in the same way, using up
all the pastry squares.
Half-fill
each pastry case with a spoonful of the cooked
leek mixture. Lay two dehydrated tomatoes on top
of each tart and then cover with the remaining
leeks.
Season well
and cook in a preheated oven, 200°C (400°F), Gas
Mark 6, for 20 minutes, covering with aluminum
foil after 10 minutes. Serve with tomatoes and
sliced red onion.
