This effervescent, nonalcoholic mocktail refresher offers the perfect balance of floral, tangy, and sweet flavors. If you’d like to turn it into a tipple, try adding a splash of gin or vodka. While we call for dried lavender, if you have access to fresh, steep a few sprigs of it in place of the dried herb—and garnish each drink with a fresh sprig, too, for a lovely, fragrant touch. You can make the syrup and cucumber-lime mixture up to a day ahead; stir in club soda just before serving.
How to Make It
Combine 1/2 cup water and sugar in a saucepan. Bring to a boil over high, stirring until sugar dissolves. Remove from heat. Add mint leaves and lavender. Steep 12 minutes. Pour through a fine wire-mesh strainer into a bowl; discard solids. Cool completely, about 10 minutes.
Combine cucumber and lime juice in a blender; process until smooth.
Stir together mint-lavender syrup, cucumber-lime mixture, and club soda in a large pitcher. Serve over ice; garnish with mint sprigs and lime wedges, if desired.
