After Campari Limoncello is the second most popular drink in Italy.
This recipe is from Nonna Peppa's oldest friend 86 year old Zia Domenica.
4 organic lemons (a bit green)
1 litre of 98% proof alcohol (if you can't find it you can use a good quality vodka)
1kg of sugar
1 litre of water
Peel the lemons so that the zest is cut into big bits and remove any white parts remaining.
Put the zest in the alcohol for 2 days (even more is fine). After this keep the alcohol and remove the zest.
Dissolve the sugar in the water (adding a bit at a time and always stirring) and then let it boil for 3 minutes. When this mixture has cooled down add the alcohol to it.
Sieve the final mixture (you can use a funnel with a fabric napkin on top so that it goes straight in the bottle).
Ready! Keep in the freezer!
