Combine mint simple syrup, lemonade, and sparkling water. Mix well and serve over ice garnished with a lemon slice and mint leaves.
Optional: For a refreshing, low alcohol cocktail add 1 ounce Anchorage Distillery vodka per 12 - 14 ounces of lemonade.
Mint Simple Syrup
Combine sugar, water, and mint leaves in a small saucepan and bring to a simmer, stirring constantly until sugar is dissolved. Take off heat and let sit for a few minutes before straining. Make sure to carefully press all liquid out of the mint. You can make syrup up to two weeks in advance; keep in the refrigerator until ready to use.
