Instructions
- Dissolve icing sugar with very little boiling water, only enough to make it just slide into butter but not be watery.
- Beat butter until soft and creamy, then add icing sugar, a little at a time and beat until white and creamy - taste before all the icing sugar has been added to see if it is sweet enough, only add the rest if it is needed.
- Add 1 tbs of boiling water, beat again, then add 1 tbs cold water.
- Continue beating until smooth, keep adding alternately a little boiling water then cold water until sugary taste has gone.
