Put the strands with coconut milk and water into a saucepan and stir constantly while bringing to the boil. Add sugar and keep stirring and simmering 10-15 minutes or until all the strands are completely dissolved.
If using agar-agar powder, sprinkle over the coconut milk, add sugar and simmer for 10 minutes. Remove from heat and stir in the coconut cream.
