Ever wondered what to do with all the lemon zest from making limoncello? I sure as heck have. All that lovely lemony-ness imbued with vodka- what a waste to toss it! I have had all my leftover zest from making this stuff for the past years, having blitzed it into a crumb like consistency, stored in my freezer for this very day of enlightment. It has come. Crema di limoncello. Hallelujah.
