Beat the yoghurt then beat in
the water until milky. Mix in the gram flour and
stir until all the lumps disappear. Add the chilies
and ginger, salt and turmeric.
Pour into a pan,
bring to the boil then simmer for 15 minutes. Remove
from the heat and pour into a large baking tray so
that it forms a thin layer.
Leave to cool then cut into
strips and roll up. Arrange the rolls in a serving
dish.
Heat the sesame oil and fry the mustard seeds
until they start crackling. Pour over the rolls and
serve garnished with the coriander and coconut.
