Mix all elements into a shaker with one big 2 inch ice cube, shake for 8-10 seconds then double strain into a coupe glass. No garnish, but a nice small basil leaf on the foam could be interesting !
For the blueberry basil syrup
1 cup of sugar, 1 cup of water, 1/2 cup blueberries muddled into the pan, simmer for 3-5 minutes while stirring constantly, you do not want a boil. Turn off heat, add 1/3 cup of fresh basil leaves. Let cool then filter.
Slightly tart, blueberry start and a nice balanced ending with a basil pop.
The aperol was replaced in this image by aperitivo orange, which is a local bitter orange liquor.
I was looking through "Cocktail codex" and found the Twist of Menton, decided to give it a spin with an idea for a blueberry basil syrup.
