Prepare your berries by washing them thoroughly, removing the stems, and cutting them into quarters. Fresh berries will release more juice and flavor than frozen ones.
Divide the strawberries between two sturdy glasses (about 4-5 berries per glass) and add half the mint leaves to each. Add 1/2 oz honey simple syrup to each glass.
Gently muddle the ingredients just until the strawberries release their juices – about 20 seconds of light pressure. You’re not trying to pulverize them, just coax out their flavor.
Fill a cocktail shaker with ice and add the gin and fresh lemon juice, dividing equally if making both drinks at once, or halving the measurements if making one at a time.
Add the muddled strawberry mixture to the shaker and shake vigorously for 20-30 seconds until the outside of the shaker becomes frosty.
Fill serving glasses with fresh ice and strain the cocktail mixture over the ice, leaving about an inch of space at the top.
Top each glass with a splash of sparkling water (about 1-2 oz) to add effervescence and lightness to the drink.
Garnish with a fresh strawberry, a sprig of mint, and a lemon wheel if desired. Serve immediately while cold and bubbly.
