On June 24th (in Italy), harvest the young walnuts. Clean them and cut each of them in 4 pieces. Be aware that green walnuts stinks are forever, so behave accordingly. I personally use some oven paper to cover the chopping board and wear old clothes.
Put all the cut walnuts in a large glass jar and cover them with the sugar. Seal the jar. Leave the jar in full sunlight for 2 days.
After 2 days, open the jar: you will find that sugar has melted into a dark liquid.
Get the cinnamon stick and the cloves ready. This my quantity (optional) for 1 liter alcohol.
Drop the spices and pour the alcohol into the jar. Leave the jar, sealed, near a window, for at least 2 months, ideally 3-4. I usually go for 90-95 days. It's important to shake it from time to time and that the jar receives some sunlight every day for a few hours.
After this long rest, it's time to filter your precious nocino! Using a funnel and a coffee filter (and some patience... yes, this liqueur is all about patience!) remove all the liquid from the jar.
Nocino will be better after at least one month in the bottles. Traditionally, the production started in June was tasted for Christmas! Personally, I find it already great after 2-3 weeks in the bottles. Enjoy!
PS at the end, only the walnuts, now completely black, will remain in the jar. Do you think that Italian tradition will throw them away? Not at all! But this is the end of this recipe.. and the beginning of a new one. Coming soon ;)
