Gradually stir in the lemon juice and whisk to combine, then add the half and half combine well.

Notes
What is Caster/fine sugar - is slightly finer and dissolves more easily than regular granulated sugar. You can make your own fine sugar just by blending granulated sugar until fine, but not powdery.You can make your own half and half but combining 1/2 cup of milk and 1/2 cup of cream, mix to combine.
