In a pitcher, combine the mint leaves and simple syrup. Using a wooden spoon, gently muddle the mint leaves, being careful not to tear them.
Stir in the lemon juice and cold water.
Add ice and the sparkling water.
Garnish each serving with a lemon wheel, frozen raspberries and additional mint leaves.
For spiked lemonade, add 1 ounce tequila to each serving.
Notes
To make simple syrup, combine ½ cup granulated sugar and ½ cup water in a small sauce pan. Cook over medium-high heat until sugar dissolves completely. Remove from heat and let cool completely before using.
