For limoncello, we use organic lemons, as there should be nothing superfluous on the zest. If your lemons are not organic, they may be coated with wax, which will increase their shelf life. Then this wax must be removed: pour boiling water over the lemons, and then rinse them under running hot water using a brush.
Do you only love cream liqueurs? Great, we make Crema di Limoncello (creamy limoncello): add 350ml double cream when the liqueur is ready and mix well. Didn't find organic lemons but met oranges? Great, make Crema di Orancello: replace 3 lemons with 2 oranges, don't forget to add the cream and, as they say in Italy, “tutto fatto”, you're done!
