Here’s how to make it at home: Peel eight lemons in long strips. Cut any white peel pith and discard. Throw the long, (likely curly) peels in a container and add vodka. Cover and let it steep for four days in room temperature. On the fourth day, pour simple syrup into the vodka-lemon peel infusion and let it sit overnight. The next day separate the peels and strain into your new container.
If you’d like to mix it into a cocktail, try this simple recipe:
1.5 oz Tessora limoncello
1 oz bourbon
1/2 oz dry vermouth
Squeeze of lemon
Stir with ice, pour over ice and garnish with a thin slice of lemon.
