In the cup of a cocktail shaker, add the lemon juice.
Gently “smack” the fresh basil on your palm and add to the shaker cup.
Taking your muddler, gentle twist into the basil, releasing the essence.
Next, add the pink grapefruit juice, simple syrup, and Hendrick’s Midsummer Solstice Gin.
Add a handful of ice, then close up the shaker.
Briskly shake your cocktail for 30 seconds, or until the shaker becomes nice and frosted. Put aside.
Fill a Double Old Fashioned glass with ice, and using either a strainer or a Cobbler-Shaker lid, strain the drink into the glass.
Garnish with your grapefruit or flowers, and enjoy!
