Pour lemon simple syrup (or lemon juice & simple syrup) in a small glass with the mint sprigs & muddle well
Refrigerate this muddled mint mixture for 30-60 minutes to infuse the mint flavor into the syrup
Fill low ball glass with ice
Pour 1.5 ounces of your mint/lemon mixture into each glass
Top with ginger ale to fill
Garnish with additional mint
*Note- you can strain out the larger pieces of mint when pouring into your glasses - I liked the tiny pieces of green color in my drink - so I wasn't too careful about getting it all out.
