Bring water and sugar to the boil, and remove
from heat when the sugar has dissolved. In a saucepan melt the butter and
then stir in the flour to a smooth paste over a low heat. While stirring,
slowly add the rosewater, syrup and liquid saffron. Continue stirring until
the mixture is a thin smooth cream. If the mixture gets too thick, add
a little warm water to it. Serve warm.
