Even though lemon is the natural accompaniment to blueberries, lime works just as well in this drink. Also, I really wanted to get a stronger blueberry taste, so I increased the amount of blueberries while doubling the total amount of simple syrup being made so we’d have enough for the entire divisional weekend games.
The sweet blueberry and lime are a great match for the tequila. Garnishing the glass with a lime gives your guests a little control to increase the tartness of their drink if they so desire.
