1.Grate
the cucumbers using a coarse grater into a colander. Place a bowl
underneath the colander and leave overnight to drain.
It is essential to remove all the juices or the dip will be watery
and separate. If you are in a hurry then place grated mixture in
a kitchen cloth, pulling up the corners to make a tight bundle.
Squeeze the bundle very hard to extract all the moisture.
2. Put grated cucumber in a mixing bowl and stir in yogurt, crushed
garlic, dill, olive oil and salt and pepper.
Cover bowl with cling film and chill for 3 hours for the flavours
to blend.
The tzatziki can be left in the refrigerator for a maximum of two
days before being used. Just before serving, stir.
3.To
serve, place three or four tbsp on a small plate or bowl.
