Homemade limoncello

Method

1. Wash the lemons well. Peel the zest from the lemons with a potato peeler, taking care not to remove any of the white pith underneath. Place the zest in a large sterilised screw-top or clip-top jar and cover with half the vodka. Seal and set aside for 2 weeks.
2. Two weeks later, put 225ml water and the sugar together in a saucepan over a low heat until the sugar has completely dissolved. Leave the sugar syrup to cool completely. (This is very important because if the sugar syrup is warm it will produce a cloudy limoncello.)
3. Pass the lemon-infused vodka through a very fine or muslin-lined sieve into a jug and mix with the remaining vodka and the sugar syrup. Pour the mixture into a sterilised bottle and seal tightly with a cork or airtight lid. Set aside in a dark cool place for 10 days, for the flavours to develop.
4. To serve as a liqueur, chill in the freezer for several hours before drinking.
