Place freezing moulds in the stand on a tray. Drain the apricots. Pour the apricots, lemon juice and aperol into a tall mixing bowl. Sift sugar over it and mix well. Puree very finely with a chopping stick.
Pour the mixture into the moulds, leaving 5-6 mm space to the edge. Close the moulds and put the sticks through the lid. Leave to freeze for about 2 hours. Before serving, briefly rinse the moulds with warm water to make them easier to remove from the mould
