Preheat the oven
to 200°C/400°F/Gas mark 6. Cut the sheets of
filo pastry into 18 squares,
measuring 10cm/4in.
Brush each filo
square very thinly with the oil, then arrange 3
squares in each
hole of a 6-hole muffin tin, placing each one at
a different angle so that they form star-shaped
baskets.
Bake for 6 to 8 minutes, until crisp
and golden. Lift the baskets out carefully and
leave them to cool on a wire rack.
Set
aside a few red currants for decoration and stir
the rest into the Greek yogurt.
Spoon this
mixture into the filo baskets. Decorate with the
reserved redcurrants and sprinkle them with the
icing sugar to serve.
