150 ml/0.25 pt milk
Salt and freshly ground black pepper
Coriander (cilantro) leaves
Method:
Heat the oil in a saucepan and stir-fry
the garlic without browning for 30 seconds. Add the potatoes and
water. Boil for 8 minutes until the potatoes are tender. Pass through
a sieve (strainer) or puree in a blender or food processor. Reheat the
puree. In a bowl, whisk the egg yolks and cornflour blended with the
cold milk. Pour in a cup of the warm soup and stir well. Add this
mixture to the remaining soup. Simmer for 4 minutes, stirring
continually. Season to taste. Ladle into warm bowls and sprinkle with
coriander leaves.
