Limoncello & raspberry semifreddo
Limoncello lends a lively kick to both the semifreddo and the sauce - a perfect chance to use up that bottle you brought back from holiday
Pare the zest from all the lemons, taking care not to include any white pith. Put the zest in a large clean jar and pour over the vodka. Cover with a tightly fitting lid and leave for a week, shaking the jar each day.
Put the sugar in a heatproof bowl and pour over the boiling water, stirring until the sugar has dissolved. Add the vodka and peels and leave for a further week, shaking the jar regularly.
Strain into decorative bottles, adding a few strips of lemon zest to each bottle.
