I’ve heard that the secret to great limoncello is to add the zest of one lime to the lemon zest before infusion. So I gave this a try to see if it adds anything. The result had a nice milky white color out of the freezer, I don’t usually get that effect but I doubt it had to do with the lime. It may be the temperature of the freezer.
The lime did exert a flavor in the finished product, it’s pretty subtle but definitely a mild lime zest flavor (not to be confused with an actual lime flavor). It has a few other off flavors, possibly because the lime wasn’t organic, and it’s a little tiny bit harsh. The lime zest adds a certain something but I don’t think it’s a real improvement so I’m declaring that adding the zest of one lime isn’t the secret to great limoncello. Here’s the breakdown:
Liquor: One bottle of 151 Proof Everclear
Liquor filtration: 5x
Lemons: 12 scrubbed Organic lemons plus the zest of one lime
Days peels and liquor rested: 56
Simple Syrup – Cups Sugar: 1.75, Cups Water: 2.5
Final filtration: 4x
