First, I place the sliced strawberries and simple syrup in the bottom of my shaker.
I use my muddler to press and smash the berries until they release their juice.
Next, I add the lemon juice and vodka (if using) to the shaker.
I fill the shaker with ice, put on the lid, and shake for about 10 seconds.
After shaking, I strain the mixture into a tall glass filled with fresh ice using a fine mesh strainer.
Finally, I pour club soda over the top and give it a gentle stir so the bubbles are not lost.
For a pretty finish, I top the drink with a lemon wheel, a strawberry slice, or a mint sprig.
