Basil and whiskey go together surprisingly well! This basil simple syrup is easy to make and is a great addition to a gin and tonic or even a glass of bubbles. I like Irish whiskey for its drinkability, my favorite is Powers.
1 C. Loosely packed basil leaves
1 C. Sugar
1 C. Water
First make the basil syrup. Heat the basil leaves, sugar, and water in a small saucepan over medium heat. Stir to dissolve the sugar. Bring to a simmer and remove from heat. Let the syrup cool completely in the pan. Strain the syrup into a jar and chill. Discard the basil leaves. The syrup can be kept in the fridge for up to two weeks.
To make a cocktail, fill a rocks glass with ice. Pour in 1 1/2 oz. whiskey, 1 oz. basil syrup, and top with club soda. Stir gently to combine. Garnish with a basil leaf.
